PCI: acpiphp: Convert acpiphp to be builtin only, not modular
Convert acpiphp to be builtin only, with no module option.
Previously, when HOTPLUG_PCI_ACPI=m, users could disable acpiphp by
removing the module or preventing it from loading. That can't be done
if acpiphp is builtin statically, so this adds an "acpiphp.disable"
kernel parameter. If a user needs to use this parameter, it is a bug,
and we want to hear about it.
[bhelgaas: fold in acpiphp.disable here, remove documentation]
