hw/pci: factor PCI reserve resources to a separate structure

Browse Source 
Factor "bus_reserve", "io_reserve", "mem_reserve", "pref32_reserve"
and "pref64_reserve" fields of the "GenPCIERootPort" structure out
to "PCIResReserve" structure, so that other PCI bridges can
reuse it to add resource reserve capability.
