Uwe Kleine-König 5162de08d1 ARM: imx: change the way imx-uarts are registered
For mx1_defconfig this yields:

	add/remove: 1/0 grow/shrink: 1/4 up/down: 49/-108 (-59)
	function                                     old     new   delta

for a random mx25 config this yields:

	add/remove: 1/0 grow/shrink: 0/5 up/down: 80/-56 (24)
