media: venus: core: Add qcm2290 DT compatible and resource data

Browse Source 
Add a qcm2290 compatible binding to the Venus core.

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

The driver is not available to firmware versions below 6.0.55 due to an
internal requirement for secure buffers.

The bandwidth tables incorporate a conservative safety margin to ensure
stability under peak DDR and interconnect load conditions.
