[PATCH next] drm/amd/display: make some symbols static

[Chen Zhou]

Make some structs and functions static to fix build warnings, parts of
warnings are as follows:

drivers/gpu/drm/amd/amdgpu/../display/dc/dce110/dce110_resource.c:744:21:
	warning: symbol 'dce110_clock_source_create' was not declared. Should it be static?
drivers/gpu/drm/amd/amdgpu/../display/dc/dce110/dce110_resource.c:768:6:
	warning: symbol 'dce110_clock_source_destroy' was not declared. Should it be static?
