xpp: More adaptations for non-PHONEDEV XPDs 

* Add IS_PHONEDEV(xpd) macro
* Reject dahdi_register_xpd()/dahdi_unregister_xpd() for non-PHONEDEV
* Make sysfs 'offhook' attribute contain '\n' if empty (no channels)
* Skip PHONEDEV related xbus_tick() parts -- we still want to process
  the end of it for the card_tick() calls.
* Remove BUG_ON() for missing phoneops
  (also remove old duplicate test for XBUS_IS...)
* Call XPD_STATE method only for PHONEDEV XPD's
