In its current form, UFS did not even probe successfully - it failed
when trying to set XO (ref_clk) to 300 MHz instead of doing so to
the ICE clk. Moreover, the missing reg-names prevented ICE from
working or being discovered at all. Fix both of these issues.

As a sidenote, the log reveals that this SoC uses UFS ICE v3.1.0.
