scsi: ufs: core: Improve the documentation of UFS data frames
In source code comments, use terminology that comes from the JEDEC UFS
standard. This makes it easier to compare the UFS driver code with the
JEDEC UFS standard. Add static_assert() statements that verify the size
of data structures defined in the UFS standard.
