Apple SoCs have an integrated NVMe controller that isn't connected over a PCIe bus. In preparation for adding support for this NVMe controller, split out the PCI support into its own file. This file is selected through a new CONFIG_NVME_PCI Kconfig option, so do a wholesale replacement of CONFIG_NVME with CONFIG_NVME_PCI.
