Subject: [PATCH 1/3] dt-bindings: gpio: lpc32xx: document interrupt bindings

Some of the LPC32xx gpios are wired directly to one of the interrupt
controllers while port 0 and port 1 share the same interrupt for their
interrupt capable gpios.

+- interrupt-names : Should be the names of irq resources. The shared port
