[PATCH edk2-platforms] Silicon/SynQuacer/DeviceTree: remove SCPI/MHU nodes

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

On our SynQuacer based platform, power state handling and other
low-level duties are handled by the secure firmware, not by the
OS, so remove the various MHU/SCPI related nodes from the device
tree.
