Andrew F. Davis 32ca8ffd5b firmware: ti_sci: Add support for firewall management 
TI-SCI message protocol provides support for controlling the firewall
configurations available in SoC.

Introduce support for the set of TI-SCI message protocol APIs that
provide us with this capability of controlling firewalls.
