drm/msm: Fix GMEM_BASE for A650 



Commit dc220915 ("drm/msm: Fix GMEM_BASE for gen8") changed the
GMEM_BASE check from adreno_is_a650_family() & adreno_is_a740_family()
to family >= ADRENO_6XX_GEN4.

This inadvertently excluded A650 (ADRENO_6XX_GEN3), causing it to report
an incorrect GMEM_BASE which results in severe rendering corruption.

Update check to also include ADRENO_6XX_GEN3 to fix A650.
