in order to verify sending SCMI commands within AML power methods.
This code lays the groundwork for testing and validating the ACPI power management features
(device frequency scaling, device power management, power capping) implemented on top
of the SCMI protocols.
To set up the platform the steps described in

is a hack required to make MHU2 protocol work on the FVP.
Boostrapping the platform through the buildroot test for rdn2 should trigger a power state change
for DMA PL330, proving that the SCMI command sent in the PS3 method was executed and received
by the SCP. The power domain in the SCP is a virtual one so it does nothing to handle the state
transition but that’s enough to verify the flow is working from ACPI power methods into SCP.
