firmware: ti_sci: Add support for processor control services
TI-SCI message protocol provides support for controlling of various physical cores available in SoC. In order to control which host is capable of controlling a physical processor core, there is a processor access control list that needs to be populated as part of the board configuration data. Introduce support for the set of TI-SCI message protocol apis that provide us with this capability of controlling physical cores.
