[v3,0/5] MTK MDP driver cleanups to prep for futher work

It most notably converts an array of MDP components to a list instead,
but also removes some unused fields.

This series of patches does some cleanup in preparation for futher work
so that hardware video decode works on 4.19 and later kernels. We are
planning on adding a dummy driver for the relevant MDP components that
will be bound together using the component framework, which will enable
calls to set up IOMMUs and LARBs, and make calls into pm_runtime.

Note: these changes depend on 757570f11fa4b0ce5472a6583de6f06e996a8527
to apply cleanly.

Changes in v3:
- Removed extra Signed-off-by: tag from commit messages.
- Removed extra line break in mtk_mdp_core.c
- Update cover letter with dependent commit

Changes in v2:
- remove unnecessary error handling labels in favor of err_m2m_register
- remove unnecessary error handling labels in favor of err_m2m_register
- rebase onto linux-next/master to pick up
