Add UFS Phy for ExynosAutov920

Like ExynosAutov9, this also uses fixed-rate clock nodes until clock driver
has been supported. The clock nodes are initialized on bootloader stage
thus we don't need to control them so far.

Changes from v4:
- Place entry in correct order instead of appending to the end.
