[PATCH] Add RGBA64 texture cpp for vc4 driver.

[Nick Kreeger]

This patch is needed to help implement half-float texturing and
rendering for the vc4 driver in mesa. This small patch introduces the
cpp value for the RGBA64 texture. A future patch will include updates to
vc4_render_cl.c to handle HDR color stores.
