7e9609d2da scsi: ufs: core: Remove HPB support 
Interest among UFS users in HPB has reduced significantly. I am not aware
of any current users of the HPB functionality. Hence remove HPB support
from the kernel.

A note: the work in JEDEC on a successor for HPB is nearing completion.
Zoned storage for UFS or ZUFS combines the UFS standard with ZBC-2.

dd11376b9f scsi: ufs: Split the drivers/scsi/ufs directory 
Split the drivers/scsi/ufs directory into 'core' and 'host' directories
under the drivers/ufs/ directory. Move shared header files into the
include/ufs/ directory. This separation makes it clear which header files
UFS drivers are allowed to include (include/ufs/*.h) and which header files
UFS drivers are not allowed to include (drivers/ufs/core/*.h).

Update the MAINTAINERS file. Add myself as a UFS reviewer.
