Use RFDIV in dm-code instead of numeric value, so-that

This patch will add common reg space for non-dm and
dm code and non-dm reg space can be accessed using
mxc_base.
This will
- get rid of __REG volatile assignments
- Make common reg_space by removing unneeded macros

DTB is encoded in big endian. When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
mismatch.
We need to use (fdt32_t *) instead of (u32 *) for a pointer of a
property value. Otherwise sparse warns "cast to restricted __be32".

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing. Follow the naming
of_get_property() from Linux.
The return type (const u32 *) is wrong. DT property values can be
strings as well as integers. This is why of_get_property/fdt_getprop
returns an opaque pointer.

The of_n_addr_cells() and of_n_size_cells() functions are useful for
getting the size of addresses in a node, but in a few places U-Boot needs
to obtain the actual property value for a node without walking up the
stack. Add functions for this and just the existing code to use it.
Add a comment to the existing ofnode functions which do not do the right

Add a function which reads resources from a device, such as the device
hardware address. This uses the "reg" property in the device.
Unlike other functions there is little sense in inlining this when
livetree is not being used because it has some logic in it and this would
just bloat the code size.

Some AHCI drivers use SCSI under the hood. Rather than making the AHCI
driver be in the SCSI uclass it makes sense to have the AHCI device create
a SCSI device as a child. That way we can handle any AHCI-specific
operations rather than trying to pretend tha the device is just SCSI.
To handle this we need to provide a way for AHCI drivers to bind a SCSI
device as its child, and probe it. Add functions for this.

With driver model we cannot have static data or assume that there is only
one device of each time. Adjust the code so that 'probe_ent' is not needed
with driver model. Add a new ahci_init_dm() function which can init AHCI

existing driver to use this new function.

Two AHCI drivers use SCSI with CONFIG_DM_SCSI. The SCSI uclass calls
scsi_low_level_init() which is implemented by ahci.c. If
CONFIG_SCSI_AHCI_PLAT is defined it does one thing and if it is not
it does something else.
We don't need to call through scsi_low_level_init() to get the init
completed. Instead, adjust the two drivers to call into AHCI directly.
Drop the post-probe init in the SCSI uclass. This means that driver model
doesn't need to use scsi_low_level_init(). It is a legacy function and
driver model should use a driver's probe() method instead.
While we are here, add a comment to the top of the file explaining what
ahci.c does.

SDMMC-PWREN is a pin to control voltage for SDMMC IO, it may
be high active or low active, the dwmmc driver always assume
the sdmmc-pwren as high active.
Kernel treat this pin as fixed regulator instead of a pin from
controller, and then it can set in dts file upon board schematic,
that's a good solution, we can also do this in u-boot.
