drm/msm/adreno: Make adreno quirks not overwrite each other
commit 13ef096e342b00e30b95a90c6c13eee1f0bec4c5 upstream.
So far the adreno quirks have all been assigned with an OR operator,
which is problematic, because they were assigned consecutive integer
values, which makes checking them with an AND operator kind of no bueno..
Switch to using BIT(n) so that only the quirks that the programmer chose
are taken into account when evaluating info->quirks & ADRENO_QUIRK_...
