Read the device tree configuration and then use it to set the
interrupt type.

This patchset is based on irq/drivers branch of tip.

Changes in v3:
  Thers is no major change in this version. Just adjust the order of the patches
  to change the DTs first. Thanks to Thomas for the suggestion.

Changes in v2:
  The patch series is based on irq/drivers branch of tip. You can simply review
  or test the patches at the link [2].

  Reverted the change to obtain params of "msi-ranges"; it's better not to
  assume the value of "#interrupt-cells" is 2, even though it's known to be
  the case. Thanks to Inochi for the comments.
