media: mtk-vcodec: Remove mtk_vcodec_release_dec_pm

There are only two lines in mtk_vcodec_release_dec_pm, using
pm_runtime_disable and put_device instead directly.

Move pm_runtime_enable outside mtk_vcodec_init_dec_pm to symmetry with
pm_runtime_disable, after that, rename mtk_vcodec_init_dec_pm to *_clk
since it only has clock operations now.
