Subject: [PATCH v4 0/5] media: venus: Add QCM2290 support with AR50_LITE core

Changes since v3:
- Fixed schema commit subject.

Changes since v2:
- Removed IS_HFI/IS_VPU macros
- checkpatch.pl --strict fixes:
  - convert macro to static inline to avoid argument reuse side effect

Changes since v1:
- Added IS_HFI macro usage
- Moved schema patch to top
- Fixed commit messages

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

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 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]
gst-launch-1.0 filesrc location=videos/xxxxx.mp4 \
  ! qtdemux name=demux demux.video_0 ! queue ! h265parse ! v4l2h265dec \
  ! videoconvert ! autovideosink

[VP9]
gst-launch-1.0 filesrc location=videos/xxxxx.webm \
  ! matroskademux ! queue ! v4l2vp9dec \
  ! videoconvert ! autovideosink

[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
