Daejun Park 756ecd96f6 FROMLIST: scsi: ufs: Add HPB 2.0 support
This patch supports the HPB 2.0.

The HPB 2.0 supports read of varying sizes from 4KB to 512KB.
In the case of Read (<= 32KB) is supported as single HPB read.
In the case of Read (36KB ~ 1MB) is supported by as a combination of
write buffer command and HPB read command to deliver more PPN.
The write buffer commands may not be issued immediately due to busy tags.
To use HPB read more aggressively, the driver can requeue the write buffer
command. The requeue threshold is implemented as timeout and can be
modified with requeue_timeout_ms entry in sysfs.
