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 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
