[PATCH] drm/amd/display: Make two functions static

[YueHaibing]

Fix sparse warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_clk_mgr.c:260:5:
 warning: symbol 'dcn10_set_dispclk' was not declared. Should it be static?
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_clk_mgr.c:286:5:
 warning: symbol 'dcn10_set_dprefclk' was not declared. Should it be static?
