[Patch 00/13] media: am437x-vpfe: overdue maintenance

[Benoit Parrot <bparrot@ti.com>]

This patch series is a collection of patches we have been carrying for a
while.

A few patches do fix actual bug and v4l2-compliance errors/warnings.
Other are drivers re-work to simplify/clarify the code for easier
maintenance.

We also include the SPDX Licensing update which seemed to have been
missed by the global script thus far.

Changes since v1:
- Address review comment from Joe, Hans and Prabhakar
- Cleaned-up the function entry debug log
- Split off the pcr change into its own patch
- Rework/combine two patches but remove code churn
- fix miscellaneous typos
