mx6: Distinguish mx6dual from mx6quad
Currently when we boot a mx6dual U-boot reports that it is a mx6quad. Report it as MX6D instead: CPU: Freescale i.MX6D rev1.2 at 792 MHz Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano babic <sbabic@denx.de> Acked-by: Otavio Salvador <otavio@ossystems.com.br>
