[ARM] 4450/1: pxa: add pxa25x_init_irq() and pxa27x_init_irq()

/* should be ok this time, I aligned this patch to your arm:pxa2.mbox */

1. move pxa25x specific IRQ initialization code to pxa25x_init_irq()
and pxa27x code to pxa27x_init_irq(), remove pxa_init_irq()

2. replace all pxa_init_irq() with their PXA25x or PXA27x specific
functions
