Subject: [PATCH 10/12] arm64: dts: qcom: sm8550: Switch UFS from
 opp-table-hz to opp-v2

Now that the non-legacy form of OPP is supported within the UFS driver,
go ahead and switch to it, adding support for more intermediate freq/power
states.

In doing so, add the CX RPMhPD under GCC to make sure at least some of
the power state requirements are *actually* propagated up the stack.
