arm64: dts: qcom: sdm630/660: Add CDSP-related nodes

Browse source

In order to enable CDSP support for SDM660 SoC:
 * add shared memory p2p nodes for CDSP
 * add CDSP-specific smmu node
 * add CDSP peripheral image loader node

Memory region for CDSP in SDM660 occupies the same spot as
TZ buffer mem defined in sdm630.dtsi (which does not have CDSP).
In sdm660.dtsi replace buffer_mem inherited from SDM630 with
cdsp_region, which is also larger in size.

SDM636 also doesn't have CDSP, so remove inherited from sdm660.dtsi
related nodes and add buffer_mem back.
