fb42387b2e dt-bindings: misc: add property to support non-secure DSP 
Add property to set DSP domain as non-secure.

ADSP/MDSP/SDSP are by default secured, where as CDSP can be either be
secured/unsecured.
non-secured Compute DSP would allow users to load unsigned process
and run hexagon instructions, but limiting access to secured hardware
within the DSP.

Based on this flag device nodes for secured and unsecured are created.

36e738bdab misc: dt-bindings: Add Qualcomm Fastrpc bindings 
The FastRPC driver implements an IPC (Inter-Processor Communication)
mechanism that allows for clients to transparently make remote method
invocations across DSP and APPS boundaries. This enables developers
to offload tasks to the DSP and free up the application processor for
other tasks.
