[PATCH v2 09/11] 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, declare the Bus Control Modules (BCMs) and the
corresponding parameters in the GPU info struct and add the
GMU_BW_VOTE feature bit to enable it.
