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]

           Say Y here if you have a system that supports PCI Hotplug using
           ACPI.
