drm/msm/a8xx: Add support for A8x GMU

Browse source 
A8x GMU configurations are very similar to A7x. Unfortunately, there are
minor shuffling in the register offsets in the GMU CX register region.
So, update the driver to use the correct register offsets on A8x hw.

Some A8x GPUs have more than 16 powerlevels on GX domain and 4 on CX
domain. To accommodate this, increase the arrays' sizes which hold gx and
cx power levels.
