Subject: [PATCH 1/2] media: venus: core: Add sdm660 DT compatible and resource struct

Add the SDM660 DT compatible and its resource structure, also
including support for the Venus pmdomains, in order to support
the Venus block in SDM630, SDM636, SDM660 and SDA variants.

This SoC features Venus 4.4 (HFI3XX), with one vcodec used for
both encoding and decoding, switched on through two GDSCs.
The core clock for this Venus chip is powered by the RPM VDD_CX
power domain.
