Now that the sequence-numbering migration is complete, rename this member
back to seq_, adding an underscore to indicate it is internal to driver
model.

Add a new function to handle the allocation of private/platform data for

With the new of-platdata, these need to be available to dt_platdata.c

Use these functions in the core code as much as possible. With this, there
are only two places where each priv/plat pointer is accessed, one for read

Most drivers use these access methods but a few do not. Update them.
In some cases the access is not permitted, so mark those with a FIXME tag
for the maintainer to check.

At present the output from this function is hard to read in SPL, due to
(intended) limitations in SPL's printf() function. Add an SPL version so

A recent change to unify the flattree/livetree code introduced a small
size increase in SPL on some boards. For example SPL code size for
px30-core-ctouch2-px30 increased by 40 bytes.
To address this we can take advantage of the fact that some of the ofnode
functions are only called a few times in SPL, so it is worth inlining
them.
Add new Kconfig options to control this. These functions are not inlined
for U-Boot proper, since this increases code size.

Some buses have their own rules which require assigning sequence numbers
with a bus-specific algorithm. For example, PCI requires that sub-buses
are numbered higher than their parent buses, meaning effectively that
parent buses must be numbered only after all of their child buses have
been numbered.
Add a uclass flag to indicate that driver model should not assign sequence
numbers. In this case, the uclass must do it.

At present each device has two sequence numbers, with 'req_seq' being
set up at bind time and 'seq' at probe time. The idea is that devices
can 'request' a sequence number and then the conflicts are resolved when
the device is probed.
This makes things complicated in a few cases, since we don't really know
what the sequence number will end up being. We want to honour the
bind-time requests if at all possible, but in fact the only source of
these at present is the devicetree aliases. Since we have the devicetree
available at bind time, we may as well just use it, in the hope that the
required processing will turn out to be useful later (i.e. the device
actually gets used).
Add a new 'sqq' member, the bind-time sequence number. It operates in
parallel to the old values for now. All devices get a valid sqq value,
i.e. it is never -1.
Drop an #ifdef while we are here.

At present this is passed a uclass ID and it has to do a lookup. The
callers all have the uclass pointer, except for the I2C uclass where the
code will soon be deleted.
Update the argument to a uclass * instead of an ID since it is more
efficient.

At present various drivers etc. access the device's 'seq' member directly.
This makes it harder to change the meaning of that member. Change access
to go through a function instead.
The drivers/i2c/lpc32xx_i2c.c file is left unchanged for now.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

The test should be checking whether $flags are non-zero and $drv_flags
contain specific flags, however these two sets of flags are separate,
and the two tests should be logically ANDed, not bitwise ANDed.

At present we use a 'node' pointer in the of-platadata phandle_n_arg
structs. This is a pointer to the struct driver_info for a particular
device, and we can use it to obtain the struct udevice pointer itself.
Since we don't know the struct udevice pointer until it is allocated in
memory, we have to fix up the phandle_n_arg.node at runtime. This is
annoying since it requires that SPL's data is writable and adds a small
amount of extra (generated) code in the dm_populate_phandle_data()
function.
Now that we can find a driver_info by its index, it is easier to put the
index in the phandle_n_arg structures.
Update dtoc to do this, add a new device_get_by_driver_info_idx() to look
up a device by drive_info index and update the tests to match.

At present of-platdata does not provide parent information. But this is
useful for I2C devices, for example, since it allows them to determine
which bus they are on.
Add support for setting the parent correctly, by storing the parent
driver_info index in dtoc and reading this in lists_bind_drivers(). This
needs multiple passes since we must process children after their parents
already have been bound.

At present we update the driver_info struct with a pointer to the device
that it created (i.e. caused to be bound). This works fine when U-Boot SPL
is stored in read-write memory. But on some platforms, such as Intel
Apollo Lake, it is not possible to update the data memory.
In any case, it is bad form to put this information in a structure that is
in the data region, since it expands the size of the binary.
Create a new driver_rt structure which holds runtime information about
drivers. Update the code to store the device pointer in this instead.
Also update the test check that this works.

With of-platdata, the driver_info struct is updated with the device
pointer when it is bound. This makes it easy for a device to be found by
its driver info with the device_get_by_driver_info() function.

Fix a bug that the function does not set *devp to NULL on failure, which

This function can be called when it is not known whether it will find
anything. This results in confusing log messages if the device is not
found. It is better for the caller to log the failure, if necessary.
