soc: apple: Add SART driver
The NVMe co-processor on the Apple M1 uses a DMA address filter called SART for some DMA transactions. This adds a simple driver used to configure the memory regions from which DMA transactions are allowed.
Unlike a real IOMMU, SART does not support any pagetables and can't be implemented inside the IOMMU subsystem using iommu_ops.
It also can't be implemented using dma_map_ops since not all DMA transactions of the NVMe controller are filtered by SART. Instead, most buffers have to be registered using the integrated NVMe IOMMU and we can't have two separate dma_map_ops implementations for a single device.

soc: apple: Add RTKit IPC library
Apple SoCs such as the M1 come with multiple embedded co-processors running proprietary firmware. Communication with those is established over a simple mailbox using the RTKit IPC protocol.
This cannot be implemented inside the mailbox subsystem since on top of communication over channels we also need support for starting, hibernating and resetting these co-processors. We also need to handle shared memory allocations differently depending on the co-processor and don't want to split that across multiple drivers.

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.
