arm64: dts: qcom: sc7280: Add support for two additional DDR frequencies

The SC7280 SoC now supports two additional frequencies. This patch
add those frequencies to the BWMON OPP table and updates the frequency
mapping table accordingly.

These changes do not impact existing platforms, as the updated mapping
only affects the highest OPP. On any given platform, this will continue
to vote for the maximum available OPP.
