[0/5] Add secure domains support

Message

This patch series adds secure domains support. If the non-secure DT property
is not added to the domain fastrpc DT node, the domain is set as secure. If
any process is getting initialized using non-secure device and the dsp channel
is secure, then the session gets rejected.
