From: Chen Wang <unicorn_wang@xxxxxxxxxxx>

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.

Also improve the code to obtain msi-ranges parameters in this patchset.

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