[PATCH v2 3/4] drm/msm/a4xx: Pass the revision information

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

Commit cc943f43ece7 ("drm/msm/adreno: warn if chip revn is verified
before being set") exposes the need of setting the GPU revision fields
prior to using the adreno_is_xxx() functions.

Pass the GPU revision information to avoid run-time warning.
