Since we need to support runtime check for different drivers, we need
to add get_cpu_rev for vf610, otherwise there will be build errors.
This patch introduces a dummy CPU id which is not read from chip
silicon. Later when we can get the real id from chip, can fix the
value of MXC_CPU_VF610 then.

Changes v2:
Take suggestion from Stefano, get_cpu_rev for vf610 should return an
ID saying dummy ID, but not 0.
