The cleanup is mostly getting rid of redundant fields in struct gpio_bank{}
as we already have them as part of bank->context now. Also, remove un-used
variable from gpio_irq_handler.

The fix include correction of _set_gpio_irqenable() implementation and fix
type mismatch of gpio trigger parameter.

It is baselined on top of Kevin's following series:

I have applied Benoit's GPIO patches in following series on top of Kevin's
before applying my changes.
