[PATCH 3/9] media: mtk-vcodec: Rewrite venc power manage interface

The args "struct mtk_vcodec_dev *" doesn't appropriate for
init/release_enc_pm functions because of component devices. For
master device, it has no "pm/clk" properties in dtsi, component
devices will init their own "pm/clk" instead. So rewrite the pm
interface with args "platform_device *" and "mtk_vcodec_pm*".
