misc: fastrpc: Add support to secure memory map
This patch adds support to secure memory allocations for DSP.
It repurposes the reserved field in struct fastrpc_invoke_args
to add attributes to invoke request, for example to setup a secure memory
map for dsp. Secure memory is assigned to DSP Virtual Machine IDs using
Qualcomm SCM calls.
