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.
