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.
