Certain Apple SoCs have additional power state controls that are using
a separate "misc" mmio interface. Currently this includes the fabric
and memory controllers on pro/max/ultra SoCs.
This series adds a driver to put those in a low power state when the
machine enters sleep. The power savings are SoC-dependent and are
around 1W.
