[0/3] gpio: lpc32xx: enable interrupts for port 3

Hi,

This series enables interrupt support for GPIOs on port 3. Those are the
GPIOs that are connected directl to an interrupt controller (sic1 or
sic2). This was tested on a custom LPC3250 design.

The binding includes support for interrupts on port 0 and port 1 but
this requires the registration of a proper irqchip and I don't have any
way to test it.

Patch 1 and 2 should probably go through the gpio tree while patch 3
should go through arm-soc. They are quite independant and this shoud
cause no issue.

  dt-bindings: gpio: lpc32xx: document interrupt bindings
  gpio: lpc32xx: enable interrupt lookup for port 3
  ARM: dts: lpc32xx: add GPIO interrupts
