Subject: [PATCH libdrm 7/7] CHROMIUM: drm_fourcc.h: Add back VENDOR_NV name

Upstream libdrm commit ab5aaf6c8eb93462c15007e9b54f4447c1ea8148 renames
DRM_FORMAT_MOD_VENDOR_NV to DRM_FORMAT_MOD_VENDOR_NVIDIA.  The old name
is used in downstream packages like minigbm, so add it back as an alias
for the new name.
