arm64: dts: qcom: sm8250: Add OPP table support to UFSHC

UFS host controller, when scaling gears, should choose appropriate
performance state of RPMh power domain controller along with clock
frequency. So let's add the OPP table support to specify both clock
frequency and RPMh performance states replacing the old "freq-table-hz"
property.
