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.
