Subject: [PATCH v3 1/3] media: mediatek: vcodec: remove vsi operation in common interface

Extend struct video shared information (vsi) to send different
parameters to scp for mt8188 architecture is changed.
Remove vsi related operation in common interface to make sure the
interface can be called by extended and non extended architecture
at the same time. The new extended interfaces with new vsi will
be introduced in later patches.
