It's useful to dump phy registers on failure to debug
link issues. Export a new ops for the ufs driver to invoke
during link failures.

phy-qcom-ufs-qmp-v3 supports SVS2 voltage scaling mode that
allows lowest power consumption in HS G1. The PHY must be put
in hibern8 state before configuring the PHY to enter SVS2 mode.
The voltage can be reduced after this to SVS2 level.
This change exposes an API that allows the UFS driver to
configure the PHY to enter SVS2 mode.
