I guess this one should be reserved to vcodec guys. I see this function
is changed at [1]. Let's keep this patchset clean.

yes, there is also asymettry when calling pm_runtime* in general,
I see in the decoder it is called from mtk_vcodec_dec_pm.c
but in the encoder it is called from mtk_vcodec_enc.c,
I think all calls to pm_runtime* should be out of the *_pm.c files
since for example 'mtk_vcodec_dec_pw_on' also do just one call to
pm_runtime_resume_and_get so this function can also be removed.

Make sense. But It may be not proper if using pm_runtime_disable
as the symmetry with mtk_vcodec_init_dec_pm in the mtk_vcodec_probe.
Maybe we should move pm_runtime_enable out from mtk_vcodec_init_dec_pm
into mtk_vcodec_probe. I could do a new patch for this. Is this ok for
you?
