gpio: davinci: Do not assume continuous IRQ numbering

Browse source 
Currently the driver assumes that the interrupts are continuous
and does platform_get_irq only once and assumes the rest are continuous,
instead call platform_get_irq for all the interrupts and store them
in an array for later use.
