[PATCH V2] drm/tegra: add MODULE_DEVICE_TABLEs

[PATCH V2] drm/tegra: add MODULE_DEVICE_TABLEs

[Stephen Warren]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

When tegra-drm.ko is built as a module, these MODULE_DEVICE_TABLEs allow
the module to be auto-loaded since the module will match the devices
instantiated from device tree.

(Notes for stable: in 3.14+, just git rm any conflicting file, since they
are added in later kernels. For 3.13 and below, manual merging will be
needed)

v2: Remove change to drm.c, since the match table there isn't used for
probing.

Thierry, I think this patch got lost? It doesn't appear in next-20140721
anyway.

Applied, sorry for the delay.
