Pull irqdomain refactoring from Grant Likely:
 "This is the long awaited simplification of irqdomain.  It gets rid of
  the different types of irq domains and instead both linear and tree
  mappings can be supported in a single domain.  Doing this removes a
  lot of special case code and makes irq domains simpler to understand
  overall"
