Add the bindings and driver changes for DSP support on the SM8650 platform in order to enable the aDSP, cDSP and MPSS subsystems to boot. Compared to SM8550, where SM8650 uses the same dual firmware files, (dtb file and main firmware) the memory zones requirement has changed: - cDSP: now requires 2 memory zones to be configured as shared between the cDSP and the HLOS subsystem - MPSS: In addition to the memory zone required for the SM8550 MPSS, another one is required to be configured for MPSS usage only. In order to handle this and avoid code duplication, the region_assign_* code patch has been made more generic and is able handle multiple DSP-only memory zones (for MPSS) or DSP-HLOS shared memory zones (cDSP) in the same region_assign functions.
