ccardimx28js: configure the serial console depending on kernel version 

SERIAL_CONSOLES_CHECK is new functionality provided by Yocto, but it
needs '/proc/consoles' supported by the kernel. Our kernel 2.6.35 does
not support '/proc/consoles' so rework the serial console configuration
to work with both kernels (2.6.35 and 3.10).
