[patch 3/3] acpi: remove dock event handling from ibm_acpi

[Kristen Accardi <kristen.c.accardi@intel.com>]

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.
