  This patchset introduces support for VDEC video hardware decoder
and VENC video hardware encoder of STMicroelectronics STM32MP25
SoC series.

This initial support implements H264 decoding, VP8 decoding and
JPEG encoding.

This has been tested on STM32MP257F-EV1 evaluation board.

version 4:
   - Fix comments from Nicolas about dropping encoder raw steps

version 3:
   - Fix remarks from Krzysztof Kozlowski:
    - drop "items", we keep simple enum in such case
    - drop second example - it is the same as the first
   - Drop unused node labels as suggested by Conor Dooley
   - Revisit min/max resolutions as suggested by Nicolas Dufresne

version 2:
   - Fix remarks from Krzysztof Kozlowski on v1:
    - single video-codec binding for both VDEC/VENC
    - get rid of "-names"
    - use of generic node name "video-codec"

version 1:
  - Initial submission

As discussed in chat, The 4K resolution didn't work correctly, so all the
resolution have been set back to 1080p.
