[ARM] 3690/1: genirq: Introduce and make use of dummy irq chip
Patch from Thomas Gleixner
From: Thomas Gleixner <tglx@linutronix.de>
ARM has a couple of really dumb interrupt controllers.
Implement a generic one and fixup the ARM migration. ARM reused
the no_irq_chip for this purpose, but this does not work out
for platforms which are not converted to the new interrupt
type handling model.
