Pull irq cleanups from Thomas Gleixner:
 "A set of cleanups for the generic interrupt subsystem:

   - Consolidate on one set of functions for the interrupt domain code
     to get rid of pointlessly duplicated code with only marginal
     different semantics.

   - Update the documentation accordingly and consolidate the coding
     style of the irqdomain header"
