This patch series adds support for the Venus video decoder/encoder block
present on the Qualcomm QCM2290.

Only video decoding is supported in this set - video encoding should
follow up in the coming weeks.

The QCM2290 integrates an AR50_LITE core, a low-power implementation of
Venus supporting H.264, HEVC (H.265), and VP9 decoding.

The series includes:
  - DT binding schema for qcom,qcm2290-venus
  - SoC integration via qcm2290.dtsi
  - Resource table definitions and frequency scaling
  - Platform capability registration for the AR50_LITE core decoding block.

Decoding was verified on the QCOM RB1 platform using GStreamer with V4L2-based
decode plugins. The following pipelines were used for playback 1280x720 and
1920x1080 H.264, HEVC and VP9 videos from https://www.elecard.com/videos.

[H.264]
gst-launch-1.0 filesrc location=videos/xxxxx.mp4 \
  ! qtdemux name=demux demux.video_0 ! queue ! h264parse ! v4l2h264dec \
  ! videoconvert ! autovideosink

[H.265]

  ! qtdemux name=demux demux.video_0 ! queue ! h265parse ! v4l2h265dec \

[VP9]

[Fluster]
The H.264 decoder was also tested using the Fluster test suite
(version: v0.4.0-12-g33566abd0964).
 Target: GStreamer-H.264-V4L2-Gst1.0, Test Suite: JVT-AVC_V1
 Result: 126/135 tests passed
 Failures:
 FM1_BT_B, FM1_FT_E, FM2_SVA_C, BA3_SVA_C, SP1_BT_A,
 SP2_BT_B, MR6_BT_B, MR7_BT_B, MR8_BT_B
