scsi: ufs: enhancements, bug fixes and debug support

This patch series adds following things:
- Gear scaling during clock scaling to save additional power
- Make clock scaling independent clock gating so that we can set lower clock gating timeout than clock scaling window
- one bug fix to clock scaling
- additional debug support

Gilad Broner (3):
scsi: ufs: skip request abort task when previous aborts failed
scsi: ufs: reduce printout for aborted requests
scsi: ufs: add host state prints in failure cases

Subhash Jadavani (3):
scsi: ufs: add load based scaling of UFS gear
scsi: ufs: don't suspend clock scaling during clock gating
scsi: ufs: kick start clock scaling only after device detection

Venkat Gopalakrishnan (2):
scsi: ufs-qcom: dump additional testbus registers
scsi: ufs: dump hw regs on link failures
