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, two more are 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.
Dependencies: None
For convenience, a regularly refreshed linux-next based git tree containing
all the SM8650 related work is available at:

Changes in v7:
- Rebased on v6.8-rc1
- Add another memory region for MPSS, in bindings, code and DT
- Kepts Krzysztof's review on bindings after agreement on irc
- Kept drivers patches reviews because it's only a miminal change (value 2 -> 3)

2.34.1
The current memory region assign only supports a single
memory region.
But new platforms introduces more regions to make the
memory requirements more flexible for various use cases.
Those new platforms also shares the memory region between the
DSP and HLOS.
To handle this, make the region assign more generic in order
to support more than a single memory region and also permit
setting the regions permissions as shared.
