scsi: ufs: add new get_scale_down_gear vops

Each ufs controller variant can work with various gear speeds that
can be supported at a low voltage corner. Add an ops function to
query the gear supported to scale down.

Also make the hibern8 entry/exit function non static as the variant
drivers might need to call hibern8 entry/exit when scaling down to
a lower gear.
