Subject: [PATCH v2 6/8] drm/msm/a6xx: add support for Adreno 660 GPU

Add adreno_is_{a660,a650_family} helpers and convert update existing
adreno_is_a650 usage based on downstream driver's logic (changing into
adreno_is_a650_family or adding adreno_is_a660).

And add the remaining changes required for A660, again based on
the downstream driver: missing GMU allocations, additional register init,
dummy hfi BW table, cp protect list, entry in gpulist table.
