The MODULE_FIRMWARE entries related to gtk20a are located in
drivers/gpu/drm/nouveau/nouveau_platform.c
This file is only built when using ARCH_TEGRA.
I'm not aware that nouveau can build a gk20a only driver, so moving
theses entries to a gk20a specific file will have the same effect at
this time.
Thx for the review.
