IRQT_FALLING will be replaced with IRQ_TYPE_FALLING_EDGE.
However I've a question. set_irq_flags is arm-only thing to change the 
status IRQ_NOREQUEST, IRQ_NOPROBE etc. Most other arches (except ppc) 
don't even bother touching IRQ_NOREQUEST. Should I change tc6393xb to 
depend on ARM or make call to set_irq_flags ARM-dependant?
