[PATCH] acpi hotplug: convert acpiphp to use generic resource code

This patch converts acpiphp to use the generic PCI resource assignment code.
It's quite large, but most of it is deleting the acpiphp_pci and acpiphp_res
files.  It's tested on an hp Integrity rx8620 (which won't work without this
patch).  Testers with other hardware welcomed.
