The address space in CDSP PAS (Peripheral Authentication Service) remoteproc node should point to the QDSP PUB address space (QDSP6...SS_PUB): 0x0a30_0000 with length of 0x10000. 0x9890_0000, value used so far, was copied from downstream DTS, is in the middle of RAM/DDR space and downstream DTS describes the PIL loader, which is a bit different interface. Datasheet says that one of the main CDSP address spaces is 0x0980_0000, which is oddly similar to 0x9890_0000, but quite different.
Assume existing value (thus downstream DTS) is not really describing the intended CDSP PAS region.
Correct the base address and length, which also moves the node to different place to keep things sorted by unit address. The diff looks big, but only the unit address and "reg" property were changed. This should have no functional impact on Linux users, because PAS loader does not use this address space at all.
