[PATCH] drm/rockchip: cdn-dp-core: Make cdn_dp_core_suspend/resume __maybe_unused

[Arnd Bergmann]

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")
