The original MSI interrupt type was hard-coded, which was not a good idea.
Now it is changed to read the device tree configuration and then set the
interrupt type.
This patchset is based on irq/drivers branch of tip.

Changes in v2:
The patch series is based on irq/drivers branch of tip.
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.
