Hector Martin 6df9d38f91 soc: apple: Add driver for Apple PMGR power state controls
Implements genpd and reset providers for downstream devices. Each
instance of the driver binds to a single register and represents a
single SoC power domain.

The driver does not currently implement all features (clockgate-only
state, misc flags), but we declare the respective registers for
documentation purposes. These features will be added as they become
useful for downstream devices.

This also creates the apple/soc tree and Kconfig submenu.

The PMGR block in Apple SoCs provides high-level power state
controls for SoC devices. This driver manages them through the
generic power domain framework, and also provides reset support.
