ARM: mxs: Change duart device to use amba-pl011
The mxs duart is actually an amba-pl011 device. This commit changes the duart device code to dynamically allocate amba-pl011 device, so that drivers/serial/amba-pl011.c can be used on mxs. Signed-off-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
