The driver still produces a warning when CONFIG_PM is disabled, an
earlier fix only partially solved this:
media/platform/mtk-mdp/mtk_mdp_core.c:72:13: error: 'mtk_mdp_clock_off' defined but not used [-Werror=unused-function]
media/platform/mtk-mdp/mtk_mdp_core.c:63:13: error: 'mtk_mdp_clock_on' defined but not used [-Werror=unused-function]
This removes the incorrect #ifdef again and instead marks the PM
functions as __maybe_unused, which reliably shuts up the warning.
Fixes: 1b06fcf56aa6 ("[media] media: mtk-mdp: fix build error")
