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.

Tested for GPIO Interrupts on da850-lcdk board.

Changes in v4:

* Corrected the gpio offset calculation from irq number
using the lookup.

Changes in v3:

* Changed irqs type from unsigned to int

Changes in v2:

* Extended the logic of using saved IRQs to unbanked IRQs
as per Grygorii's suggestion.
