[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.
