With the new static annotation, the compiler warns when the functions
are actually unused:
drivers/gpu/drm/rockchip/cdn-dp-core.c:1123:12: error: 'cdn_dp_resume' defined
but not used [-Werror=unused-function]
1123 | static int cdn_dp_resume(struct device *dev)
| ^~~~~~~~~~~~~
Mark them __maybe_unused to suppress that warning as well.
Fixes: 7c49abb4c2f8 ("drm/rockchip: cdn-dp-core: Make
cdn_dp_core_suspend/resume static")
