[v3,00/12] misc: fastrpc: Add missing DSP FastRPC features

This patchset adds below DSP FastRPC features that have been missing in
upstream fastrpc driver and also cleans up channel context structure with kref.

- Add ablity to reflect if the DSP domain is secure/unsecure by creating
 seperate device nodes for secured domain, this would used by SE policy
 to restrict applications loading process on the DSP.
- Add new IOCTL to get DSP capabilites
- Add IOCTL to support mapping memory on the DSP.
- Add support for allocating secure memory for DSP
- Handle fdlist in put args
- Handle dma fds in invoke request.

Tested this series on DragonBoard 845c with TensoFlowLite.

Changes since v2:
- Add support for Secure Memory allocations.
- added handling fdlist and dmalist in and after invoke.
- removed unnecessary debug log
- removed dependency on yaml bindings and added new bindings to .txt
