Apple SoCs have PMGR blocks that control a bunch of power-related features. Besides the existing device power state controls (which are very uniform and handled by apple-pmgr-pwrstate), we also need to manage more random registers such as SoC-wide fabric and memory controller power states, which have a different interface. Add a driver for these kitchen sink controls. Right now it implements fabric and memory controller power state switching on system standby/s2idle, which saves about 1W of power or so on t60xx platforms.
