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 v2:
- Rename VPFE_MAX_ACTIVE_FMT to VPFE_NUM_FORMATS and corrected the
  comments
- Move the "Remove print_fourcc helper" patch to the end of the series
  and rebase it on the pending v4l2_fourcc_conv macros patches

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
