ARM: mach-imx: mm-imx5: Retrieve tzic base address from dt
As mx53 is a dt-only SoC, we should retrieve the tzic base address from the device tree, instead of using the old MX53_IO_ADDRESS method. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
