scsi: ufs: fix endianness sparse warnings
Fix many warnings with incorrect endian assumptions
which makes the code unportable to new architectures.
The UFS specification defines the byte order as big-endian
for UPIU structure and little-endian for the host controller
transfer/task management descriptors.
