Ouch! It's all about the GPIO numbers...

This occurred when I re-based to Stefano's tree and will require
another patch to keep the BANK:OFFSET numbering scheme. There's a
patch lingering in Dirk's tree that defines IMX_GPIO_NR() in gpio.h.

See http://lists.denx.de/pipermail/u-boot/2012-January/116866.html
for details.

I was hoping to get some feedback before generating a patch and
revising this patch (and removing GPIO_3_19 macro):

That said, I'll revise and re-send along with a patch adding
support for:
	GPIO_NUMBER(port,index)
	GPIO_PORT(number)
	GPIO_INDEX(number)
