hw/acpi: Consolidate build_mcfg to pci.c

Browse source 
Now we have two identical build_mcfg functions.

Consolidate them in acpi/pci.c.

Signed-off-by: Wei Yang <richardw.yang@linux.intel.com>

v4:
  * ACPI_PCI depends on both ACPI and PCI
  * rebase on latest master, adjust arm Kconfig
v3:
  * adjust changelog based on Igor's suggestion
