The register HW_SSP_VERSION is broken for ssp version detection, as the address of the register is different between imx23 and imx28. Let's use platform_device_id to detect the device, so that the use of cpu_is_xxx can be removed. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Chris Ball <cjb@laptop.org>
