[PATCH] PCI Hotplug: add common acpi functions to core
shpchprm_acpi.c and pciehprm_acpi.c are nearly identical. In addition,
there are functions in both these files that are also in acpiphp_glue.c.
This patch will remove duplicate functions from shpchp, pciehp, and
acpiphp and move this functionality to pci_hotplug, as it is not
hardware specific. Get rid of shpchprm* and pciehprm* files since they
are no longer needed. shpchprm_nonacpi.c and pciehprm_nonacpi.c are
identical, as well as shpchprm_legacy.c and can be replaced with a
macro.
This patch also changes acpiphp to use the common hpp code.
