arm64: dts: amlogic: meson-gxm: add the Mali OPP table and use DVFS

Browse source

Add the OPP table for the Mali-T820 GPU and drop the hardcoded initial
clock configuration. This enables GPU DVFS and thus saves power when the
GPU is not in use while still being able switch to a higher clock on
demand.
