This adds support for the (rather quirky) NVMe storage controller integrated on Apple SoCs. This makes it possible to boot from the NVMe storage that is present on all the M1 machines that Apple has released so far.
The series has been designed to have as little impact on the existing NVMe support as possible. It splits out the PCIe-specific bits in its own file/driver and adds a platform driver for the Apple controller. This platform driver handles all the quirkiness through driver ops. The existing logic is retained when the driver ops aren't set. I've tested this on a firefly-rk3399 board with: nvme0 at pci1 dev 0 function 0 "Silicon Motion SM2260 NVMe" rev 0x03: msix, NVMe 1.2 nvme0: ADATA SX8000NP, firmware C2.2.1, serial 2H1220011170 (for those not familliar with OpenBSD, that's an ADATA SX8000NP NVMe M.2 SSD with a Silicon Motion controller) This patch series depends on the Apple M1 power management controller support series:
