[PATCH] acpi: remove dock event handling from ibm_acpi

Remove dock station support from ibm_acpi by default.  This support has
been put into acpiphp instead.  Allow ibm_acpi to continue to provide
docking station support via config option for laptops/docking stations
that are not supported by acpiphp.
