Subject: [PATCH] drm: add missing MODULE_DESCRIPTION() macros

On x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/gpu/drm/gud/gud.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/gpu/drm/drm_panel_orientation_quirks.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/gpu/drm/drm_mipi_dbi.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/gpu/drm/i915/kvmgt.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/gpu/drm/udl/udl.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

For consistency this includes drivers/gpu/drm/drm_simple_kms_helper.c
since it contains a MODULE_LICENSE() even though it isn't built as a
separate module -- it is always built as part of drm_kms_helper and
drm_kms_helper_common.c already provides a MODULE_DESCRIPTION for that
module.

This is the last in a set of patches to drivers/gpu/drm. The
preceeding patches cleaned up subdirectiries that had more than one
issue. This patch cleans up the stragglers. Let me know if any of
these modifications need to segregated into separate patches.
