9b87181fd2 firmware: ti_sci: Add support for clock control
In general, we expect to function at a device level of abstraction,
however, for proper operation of hardware blocks, many clocks directly
supplying the hardware block needs to be queried or configured.

Introduce support for the set of SCI message protocol support that
provide us with this capability.

7bc330452c firmware: ti_sci: Add support for device control
TI-SCI message protocol provides support for management of various
hardware entitites within the SoC. Introduce the fundamental
device management capability support to the driver protocol
as part of this change.

32cd25128b 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 the K3
family AM654 SoC to communicate between various compute processors with
a central system controller entity.

The 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.

This is mostly derived from the TI SCI driver in Linux located at
drivers/firmware/ti_sci.c.
