firmware: Add basic support for TI System Control Interface (TI-SCI) protocol 



Texas Instrument's System Control Interface (TI-SCI) Message Protocol
is used in Texas Instrument's System on Chip (SoC) such as those
in keystone family K2G SoC to communicate between various compute
processors with a central system controller entity.

TI-SCI message protocol provides support for management of various
hardware entities within the SoC. Add support driver to allow
communication with system controller entity within the SoC using the
mailbox client.

We introduce the basic registration and query capability for the
driver protocol as part of this change. Subsequent patches add in
functionality specific to the TI-SCI features.

	  TI System Control Interface (TISCI) Message Protocol is used to manage

	  compute systems such as ARM, DSP etc with the system controller in

	  complex System on Chip(SoC) such as those found on certain keystone

	  generation SoC from TI.



	  System controller provides various facilities including power

	  management function support.



	  This protocol library is used by client drivers to use the features

	  provided by the system controller.
