Merge tag 'mxs-sparse-irq' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc2

The series adds irqdomain support for mach-mxs and then enables
sparse-irq.  It dependes on pull request mxs-dt-3.7.

* tag 'mxs-sparse-irq' of git://git.linaro.org/people/shawnguo/linux-2.6:
  ARM: mxs: remove mach/irqs.h
  ARM: mxs: select SPARSE_IRQ
  ARM: mxs: adopt irq_domain support for icoll driver
  ARM: mxs: select MULTI_IRQ_HANDLER
  ARM: mxs: retrieve timer irq from device tree
  gpio/mxs: adopt irq_domain support for mxs gpio driver
