Stanley Chu 722adbbd70 scsi: ufs: ufs-mediatek: gate ref-clk during Auto-Hibern8
In current UFS driver design, hba->uic_link_state will not be changed after
link enters Hibern8 state by Auto-Hibern8 mechanism.  In this case,
reference clock gating will be skipped unless special handling is
implemented in vendor's callbacks.

Support reference clock gating during Auto-Hibern8 period in MediaTek
Chipsets: If link state is already in Hibern8 while Auto-Hibern8 feature is
enabled, gate reference clock in setup_clocks callback.
