ACPI: pci_root: pass acpi_pci_root to arch-specific scan
The acpi_pci_root structure contains all the individual items (acpi_device, domain, bus number) we pass to pci_acpi_scan_root(), so just pass the single acpi_pci_root pointer directly. This will make it easier to add _CBA support later. For _CBA, we need the entire downstream bus range, not just the base bus number. We have that in the acpi_pci_root structure, so passing the pointer makes it available to the arch-specific code.
