Based on Jiang Liu's common interface to support PCI host bridge
init and refactoring of MMCONFIG, this patch using information
from ACPI MCFG table and IO/irq resources from _CRS to init
ARM64 PCI hostbridge, then PCI will work on ARM64.

This patch is based on Mark Salter and Tomasz Nowicki's work.

HAVE_PCI_ECAM and GENERIC_PCI_ECAM should be selected by platform.

OK.

I think we should depend on PCI too.

Since ACPI depends on PCI, denpends on
PCI is duplicate I think.
