drm/msm/a6xx: Use CX AO Counter register for timestamp on a750 GPUs
The a750 uses the GMU CX AO Counters instead of the GMU_ALWAYS_ON_COUNTER
register on A6xx and other A7xx GPUs, use it when running a A750 GPU.
The GMU_ALWAYS_ON_COUNTER at offset 0x1f888 doesn't seem to exist
on the SM8650 A750 GMU and returns 0, but the CX AO counter at offset
0x1f880 returns some proper timestamp data.
