Instead of using the hard-coded value of 0x1f, use 'TASK_TAG'
macro instead to construct the ucd_req_ptr->header.dword_0
This is in sync with what the Linux UFS driver does, i.e.
set the byte0 equal to TASK_TAG (see [1]).
Setting it to a fixed value of 0x1f is wrong as we define
TASK_TAG as 0 inside u-boot ufs framework. So, instead we
should use the macro value directly.

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU
can expect 64-bit data from the device tree parser, so use
dev_read_addr_ptr instead of the dev_read_addr function in the
various files in the drivers directory that cast to a pointer.
As we are there also streamline the error response to -EINVAL on return.

At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks. Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

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.

This header file should not be included in other header files. Remove it
and use a forward declaration instead.
Also drop asm/io.h

The implementation of dma_map_single() and dma_unmap_single() is
exactly the same for all the architectures that support them.
Factor them out to <linux/dma-mapping.h>, and make all drivers to
include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>.
If we need to differentiate them for some architectures, we can
move the generic definitions to <asm-generic/dma-mapping.h>.
Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

Add Support for UFS Host Controller Interface (UFSHCI) for communicating
with Universal Flash Storage (UFS) devices. The steps to initialize the
host controller interface are the following:
- Initiate the Host Controller Initialization process by writing to the
Host controller enable register.
- Configure the Host Controller base address registers by allocating a
host memory space and related data structures.
- Unipro link startup procedure
- Check for connected device
- Configure UFS host controller to process requests
Also register this host controller as a SCSI host controller.
Taken from Linux Kernel v5.2 (drivers/scsi/ufs/ufshcd.c) and ported to
U-boot.
