firmware: ti_sci: Add support for NAVSS resource management

Texas Instruments' System Control Interface (TI-SCI) Message Protocol
abstracts management of NAVSS resources, like PSI-L pairing and
unpairing, UDMAP tx/rx/flow configuration and Rings.

This patch adds support for requesting and configuring such resources
from TI-SCI firmware.
