drm/amdgpu: Clean up mmhub functions for aldebaran

Add more function pointers to amdgpu_mmhub_funcs. ASIC specific
implementation of most mmhub functions are called from a general
function pointer, instead of calling different function for
different ASIC.

V2: Split patch into upstreamable and aldebaran
