MX31: change return value of get_cpu_rev
Drop warnings in get_cpu_rev and changes the return value (a u32 instead of char * is returned) of the function to be coherent with other processors. Signed-off-by: Stefano Babic <sbabic@denx.de> CC: Detlev Zundel <dzu@denx.de> CC: Fabio Estevam <fabio.estevam@freescale.com>
