pci: avoid accidental clobbering of regs on some fdt platforms

Most pci controllers will just have a single reg for the config space,
but others (e.g., on Apple Silicon) may have more following that to
describe, e.g., controller port space. Bump the "ranges" rid space up
to avoid overriding these other memory resources.

pci_host_generic: Enumerate resource ranges under bootverbose

Previously ranges were only enumerated for the FDT attachment but not
ACPI. This commit moves the enumeration to the shared attach routine
so it is done for both. While here, don't list empty ranges but do
include the resource type for each range.

positions of bus0. Mitigate the issue by filtering out

pci_host_generic_fdt.c: Add support for mapping dts nodes to PCI devices

Some arm64 SoCs have nodes in their fdts that describe devices
connected to the internal PCI bus. One such SoC is Freescale LS1028A.
It expects the nodes to be mapped to devices enumerated using the standard
PCI method. Mapping is done by reading device and function ids from "reg"
property. Information is dts is used to describe MDIO/PHY connected
to a given interface.
