The logic for requesting interrupts is duplicated for each interrupt. In
the upcoming patches that introduces support for multiport, it would be
better to clean up the duplication before reading mulitport related
interrupts.

Refactor interrupt setup call by adding a new helper function for
requesting the wakeup interrupts. To simplify implementation, make
the display name same as the interrupt name expected in Device tree.

As far I can see, you only replaced "DT" with "Device tree" in the
commit message. For changes like that you could have kept my
Reviewed-by tag (but I appreciate that you dropped it from some of the
others):
