Subject: [PATCH] drm/rockchip: cdn-dp-core: Fix cdn_dp_resume unused warning

From: Palmer Dabbelt <palmerdabbelt@...gle.com>

cdn_dp_resume is only used under PM_SLEEP, and now that it's static an
unused function warning is triggered undner !PM_SLEEP.  This
conditionally enables the function to avoid the warning.

Fixes: 7c49abb4c2f8 ("drm/rockchip: cdn-dp-core: Make cdn_dp_core_suspend/resume static")
