drm/msm: Fix GMEM_BASE for A650
Commit dc220915ddb2 ("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.
Fixes: dc220915ddb2 ("drm/msm: Fix GMEM_BASE for gen8")
