acpi: Extract crs build form acpi_build.c

Browse source 
Extract crs build form acpi_build.c, the function could also be used
to build the crs for pxbs for arm. The resources are composed by two parts:
1. The bar space of pci-bridge/pcie-root-ports
2. The resources needed by devices behind PXBs.
The base and limit of memory/io are obtained from the config via two APIs:
pci_bridge_get_base and pci_bridge_get_limit
