msm: mdss: Request max register bus bandwidth for PP LUTs during resume

There are a couple postprocessing features that are LUT based features,
and they require a lot of register accesses to configure the hardware.
During the first resume display commit, when all registers are
reconfigured, if any of the LUT based PP features are enabled, then we
will request maximum bus bandwidth to speed up the accesses.
