[PATCH v3, 05/10] media: mtk-vcodec: mtk-vcodec: Rewrite venc power manage interface

[Irui Wang <irui.wang@xxxxxxxxxxxx>]

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