Since we need to support runtime check for different drivers, we need to add get_cpu_rev for vf610.
This patch only introduce a empty implementation to avoid build errors, later more stuff can be added if need to check vf610 cpu types.

If there is really no way to get the cpu revision from the SOC, I suggest we use the same approach of MXC_CPU_MX6SOLO with a "dummy" cpu. Something like :
#define MXC_CPU_VF610 0xF6 /* dummy CPU */
"F6" from vF610, of course, instead of returning 0.
