Some SCSI devices like UFS use DMA for executing scsi commands and hence
need to know the direction of transfer of the dma. Add a dma_dir element
to the command structure to facilitate this.

The UFS SCSI device LUNs are observed to return failure the first time a
unit ready inquiry is sent and pass on the second try. Send this
inquiry 3 times to make sure device is ready.

Add max_bytes_per_req to scsi_platdata to enable the host driver to limit
the number of bytes that can be read/written per request.

Before the patch scsi would report the same device number for all SCSI
devices, e.g.

  Device 0: (1:0) Vendor: ATA Prod.: Crucial_CT128M55 Rev: MU01
            Type: Hard Disk
            Capacity: 122104.3 MB = 119.2 GB (250069680 x 512)
  Device 0: (1:0) Vendor: ATA Prod.:  Rev:
            Type: Hard Disk
            Capacity: not available

With the patch the same device number is reported as is used in
scsi_read():

  Device 0: (1:0) Vendor: ATA Prod.: Crucial_CT128M55 Rev: MU01
            Type: Hard Disk
            Capacity: 122104.3 MB = 119.2 GB (250069680 x 512)
  Device 1: (1:0) Vendor: ATA Prod.:  Rev:
            Type: Hard Disk
            Capacity: not available

part_init() is currently called in every DM BLK driver, either
in its bind() or probe() method. However we can use the BLK
uclass driver's post_probe() method to do it automatically.

Update all DM BLK drivers to adopt this change.

In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's <inttypes.h>.
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE
based on a list of enabled options.  Moving HAVE_BLOCK_DEVICE to
Kconfig allows us to drastically shrink the logic in
config_fallbacks.h
