Uclass API provides a few functions for get/find the device.
To provide a complete function set of uclass-internal functions,
for use by the drivers, the function uclass_get_device_tail()
should be non-static.

This commit extends the driver model device's API by function:
- dev_get_uclass_name()
And this function returns the device's uclass driver name if:
- given dev pointer, is non_NULL
otherwise, the NULL pointer is returned.

This commit extends the driver model uclass's API by function:
- uclass_get_device_by_name()
And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists,
- device probe, doesn't return an error.
The returned device is activated and ready to use.
Note:
This function returns the first device, which name is equal
to the given one. This means, that using this function you must
assume, that the device name is unique in the given uclass's ID
device list.

This commit adds 'uclass_platdata' field to 'struct udevice', which
can be automatically allocated at bind. The allocation size is defined
in 'struct uclass_driver' as 'per_device_platdata_auto_alloc_size'.
New device's flag is added: DM_FLAG_ALLOC_UCLASS_PDATA, which is used
for memory freeing at device unbind method.
As for other udevice's fields, a complementary function is added:
- dev_get_uclass_platdata()

This commit extends the uclass-internal functions by:
- uclass_find_first_device()
- uclass_find_next_device()
For both functions, the returned device is not probed.
After some cleanup, the above functions are called by:
- uclass_first_device()
- uclass_next_device()
for which, the returned device is probed.

Need to check value of spi_setup_slave and spi_setup_slave_fdt.
If their return value 'bus' is NULL, there is no need to pass it
to following spi_flash_probe_tail.
If 'bus' is null, the original function flow is as following:
spi_flash_probe
|->spi_setup_slave
|->spi_probe_bus_tail
|->spi_flash_probe_slave
|->spi_free_slave
Alougth check the pointer in spi_free_slave is ok, checking the return value
of spi_setup_slave and spi_setup_slave_fdt is better.

to show the link status, so the patch fixes it.
2. Increase the delay time to make sure that link training

4. For LS2085a DBI_RO_WR_EN bit is cleared as default, so we

commit aed2fbef5e9a0ab5a7cd01e742039a962f0b24ef
"dm: serial: Tidy up the pl01x driver"
caused a regression on (real hardware) PL010 by omitting
to update the line control register when switching baudrate.
Fix this by inlining the missing write to the baud control
register.
Also renaming the set_line_control() function to
pl011_set_line_control() since this function is clearly
PL011-specific, and it won't suffice to call that to
set up line control.
Tested on the Integrator/AP hardware.

Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have
interrupts enabled by default. If the interrupt is not treated later by
the OS and the PHY's interrupt line is enabled and shared with other
interrupts, the system will get an interrupt storm. This patch disables
the interrupt for PHY devices that use one of the current Realtek
Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L)
have the interrupt masked. In this case, the functionality of the PHY
should not be afected since this patch brings INER and INSR registers to
their default values.

According to the MPC8555/MPC8541 reference manual the SS_EN (source
synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set
during initialization.
>From section 9.4.1.8 of that manual:
Source synchronous enable. This bit field must be set during
initialization. See Section 9.6.1, "DDR SDRAM Initialization
Sequence," details.
0 - Reserved
1 - The address and command are sent to the DDR SDRAMs source
synchronously.
In addition, Freescale application note AN2805 is also very clear that
this bit must be set.
This patch reverts a change introduced by commit
457caecdbca3df21a93abff19eab12dbc61b7897.
Testing Done:
Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS
and inspected the generated assembly code to verify the SS_EN bit was being
set. There is one extra instruction emitted:
fff9b774: 65 29 80 00 oris r9,r9,32768
Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no
additional instructions were emitted related to this patch.
Booted an image on a MPC8541 based board successfully.

Adjust the error handling to use errno.h instead of returning -1. Change
leaf functions to pass in the arguments they require rather than struct
eth_device. Apart from simplifying the code it makes is easier to reuse
these functions for driver model, since mostly they actually only use
struct dw_eth_priv (which we can keep).
Create a stub for each Ethernet operation function. This will allow use to
