[PATCH next] drm/amd/display: make non-global functions static

[Chen Zhou <chenzhou10@huawei.com>]

Fix sparse warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:964:5:
	warning: symbol 'shift_border_left_to_dst' was not declared. Should it be static?
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:975:6:
	warning: symbol 'restore_border_left_from_dst' was not declared. Should it be static?

Fixes: 89d07b662f5e (drm/amd/display: fix 270 degree rotation for mixed-SLS mode)
