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.
