PCI: Allow manual resource allocation for PCI hotplug bridges
At the moment only PCI-E briges can be flagged as hotplug, thus allowing manual resource preallocation via pci=hpmemsize=nnM and pci=hpiosize=nnM kernel parameters. Some PCI hotplug bridges, e.g. PLX 6254 can also benefit from this functionalily, as kernel fails to properly allocate their resources when hotplug device is added and PCI bus is rescanned. This patch adds header quirk for PLX 6254 that marks this bridge as hotplug. Other PCI bridges with similar problems can use it as well.
