This is the remaining MFD fixes for 3.6, with 5 pending fixes: 

- A tps65217 build error fix.
 - A lcp_ich regression fix caused by the MFD driver failing to initialize the
   watchdog sub device due to ACPI conflicts.
 - 2 MAX77693 interrupt handling bug fixes.
 - An MFD core fix, adding an IRQ domain argument to the MFD device addition
   API in order to prevent silent and potentially harmful remapping behaviour
   changes for drivers supporting non-DT platforms.
