[PATCH 3/3] ARM: mach-imx: mm-imx5: Retrieve iomuxc base address from dt

[festevam@gmail.com (Fabio Estevam)]

From: Fabio Estevam <fabio.estevam@freescale.com>

As mx53 is a dt-only SoC, we should retrieve the iomuxc base address from the 
device tree, instead of using the old MX53_IO_ADDRESS method.
