[GIT PULL FOR v5.12] ti-vpe: cal: prepare for adding MC support

[Hans Verkuil <hverkuil@xs4all.nl>]

This PR merges all except for the final patch of the ti-vpe cal MC series:

https://patchwork.linuxtv.org/project/linux-media/cover/20201206235353.26968-1-laurent.pinchart@ideasonboard.com/

It is very likely that by the time this PR can be merged there will be a v2
of this PR containing the last patch as well, but for now I want to post this
to ensure that at least these patches will be merged.

Regards,

	Hans
