Nouveau - Nov 2015 - [PATCH v2] nouveau: arm: Add MODULE_FIRMWARE for gk20a

This patch is needed by initramfs tools to detect
the required firmware files for the module.

This patch tests for either TEGRA_124_SOC or TEGRA_132_SOC
for the firmwares related to the Tegra K1 generation.

v2: move the MODULE_FIRMWARE to the nvidia_platform.c file.
 This will avoid to test for NOUVEAU_PLATFORM_DRIVER

Thx for the review.
FYI I've tested the patch on top of 4.3+ kernels, and the initramfs
generated with dracut works as expected.

Is there any other concern with this patch ?

It's certainly late for 4.4,I would expect it to hit kernel 4.3 at some
point, but I don't think everything is wired from userspace(Xorg/Wayland)
wrt dGPU support.
So It could also wait for 4.5.
What do you think ?

Thx
