mx6cuboxi: Fix the console variable

Do not pass the console baudrate to the 'console' variable
to avoid the baudrate being passed twice when extlinux.conf
contains the standard: console=${console},${baudrate} format.

cat /proc/cmdline
root=PARTUUID=00000000-01 rootwait rw console=ttymxc0,115200,115200
