[PATCH v2 05/14] drm/msm/adreno: Disable has_cached_coherent for A610/A619_holi

[Konrad Dybcio]

These SKUs don't support the feature. Disable it to make the GPU stop
crashing after almost each and every submission - the received data on
the GPU end was simply incomplete in garbled, resulting in almost nothing
being executed properly.
