clk: hi3660: Mark clk_gate_ufs_subsys as critical
commit 9f77a60669d13ed4ddfa6cd7374c9d88da378ffa upstream.
clk_gate_ufs_subsys is a system bus clock, turning off it will
introduce lockup issue during system suspend flow. Let's mark
clk_gate_ufs_subsys as critical clock, thus keeps it on during
system suspend and resume.
