Subject: [PATCH] drm: armada: constify drm_prop_enum_list structures.

drm_prop_enum_lists are not supposed to change at runtime. All functions
working with drm_prop_enum_list provided by <drm/drm_property.h> work
with
const drm_prop_enum_list. So mark the non-const structs as const.

File size before:
text data bss dec hex filename
9629 744 0 10373 2885 drivers/gpu/drm/armada/armada_crtc.o

File size After adding 'const':
text data bss dec hex filename
9757 616 0 10373 2885 drivers/gpu/drm/armada/armada_crtc.o
