[PATCH 00/14] irqchip: crossbar: driver fixes

This series does some cleanup and provides support for
hardwired IRQ and crossbar definitions.

On certain platforms such as DRA7, SPIs 0, 1, 2, 3, 5, 6, 10,
131, 132, 133 are direct wired to hardware blocks bypassing
crossbar. This quirky implementation is *NOT* supposed to be the
expectation of crossbar hardware usage. This series adds support
to represent such hard-wired irqs through DT and avoid generic
allocation/programming of crossbar in the driver.

This way of supporting hard-wired irqs was a result of
the below discussions.

Based on linux-next next-20140602 tag + Tony's omap-for-v3.16/crossbar branch.
