Greg Ungerer a405f833f4 m68knommu: support the external GPIO based interrupts of the 5272 
The external GPIO interrupts of the ColdFire 5272 SoC are edge triggered,
unlike the internal interrupt sources (which are level triggered).

Add proper support for these interrupts.

Greg Ungerer 04570b4621 m68knommu: stop using __do_IRQ 
The use of __do_IRQ is deprecated, so lets stop using it.
Generally the interrupts on the supported processors here are
level triggered, so this is strait forward to switch over to
using the standard handle_level_irq flow handler. (Although
some ColdFire parts support edge triggered GPIO line  interrupts
we have no support for them yet).

Greg Ungerer 9075216d2c m68knommu: create a speciailized ColdFire 5272 interrupt controller 
The ColdFire 5272 CPU has a very different interrupt controller than
any of the other ColdFire parts. It needs its own controller code to
correctly setup and ack interrupts.
