Subject: [PATCH v6 5/7] media: venus: core: Add qcm2290 DT compatible and resource data

Add a qcm2290 compatible binding to the Cenus core.

The maximum concurrency is video decode at 1920x1080 (FullHD) with video
encode at 1280x720 (HD).

The encoder is not available to firmware versions below 6.0.54 due to an
internal requirement for secure buffers.
