[Mesa-stable] [PATCH 1/6] anv: remove internal 'validate' layer

From: Emil Velikov <emil.velikov at collabora.com>
Presently the layer has only a single entry point. As mentioned by Jason the
function does not validate anything that isn't checked elsewhere, thus we can
drop the whole thing.

Patch replaces "anv: hook internal validate layer only for debug builds"
