PCI hotplug: acpiphp should be linked after vendor drivers 

As a followup to 71a082efc9, it's conceivable
that some vendors may expose PCI hotplug functionality through both vendor
mechanisms and ACPI. The native mechanism will generally be a superset of
any functionality provided via ACPI, so the acpiphp driver should always
be initialised after any others. Change the link order such that acpiphp
will not be initialised until any other statically linked drivers have had
an opportunity to claim the hardware.
