drm/mediatek: Fix PM reference leak in mtk_crtc_ddp_hw_init()
[ Upstream commit 69777e6ca3
]
pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.
