Commit Message

Yunfei Dong Dec. 17, 2021, 1:55 a.m. UTC 
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.
