Hi Vinod,

This series adds two new phy modes to support UFS HIBERN8_ENTER and
HIBERN8_EXIT.

This is used for UFS phys that need to program specific values when entering
and exiting from ufs hibern8 state. Once such platform that needs to do this is
gs101 SoC found on Pixel 6.

phy-gs101-ufs is also updated to include these hibern8 enter/exit specific tuning
values.

Note: a separate series will be sent for ufs-exynos driver that makes use of
this new UFS phy functionality.

regards,

Peter
