Subject: [PATCH 1/1] Input: ab8500-ponkey: Make the distinction between DT and non-DT boots

If we're booting with Device Tree enabled, we want the IRQ numbers to
be taken and translated from the Device Tree binary. If not, they
should be taken from the resource allocation defined in the AB8500 MFD
core driver.
