[PATCH RFC 6/8] drm/msm: adreno: enable GMU bandwidth for A740 and A750

[Neil Armstrong]

Now all the DDR bandwidth voting via the GPU Management Unit (GMU)
is in place, let's declare the Bus Control Modules (BCMs) and
it's parameters in the GPU info struct and add the GMU_BW_VOTE
quirk to enable it.
