Ekansh Gupta 5e305b5986 misc: fastrpc: Restrict untrusted app to attach to privileged PD 
commit bab2f5e8fd upstream.

Untrusted application with access to only non-secure fastrpc device
node can attach to root_pd or static PDs if it can make the respective
init request. This can cause problems as the untrusted application
can send bad requests to root_pd or static PDs. Add changes to reject
attach to privileged PDs if the request is being made using non-secure
fastrpc device node.

Fixes: 0871561055 ("misc: fastrpc: Add support for audiopd")
