I've introduced an LPC2K_GPIO(port,pin) macro for that, and already use
it for the IRQs too. I like your suggestion!

However, since now we're not using explicit GPIO numbers anymore,
wouldn't you agree it would be better to make the above:

#define P0_0_RD1		MFP_CFG(LPC2K_GPIO(0, 0), AF1)

instead of still using the GPIOx prefix?
