[ARM] pxa: merge assignment of set_wake into pxa_init_{irq,gpio}()

Browse source 
To further clean up the GPIO and IRQ structure:

1. pxa_init_irq_gpio() and pxa_init_gpio() combines into a single
   function pxa_init_gpio()

2. assignment of set_wake merged into pxa_init_{irq,gpio}() as
   an argument
