Since we want to have consistent i2c numbering, we cannot force the bus->req_seq because. If for instance we have 3 buses numbered from 0 to 2 with i2c0 enabled, i2c1 disabled and i2c2 enabled; i2c2 can be selected using 'i2c dev 1' and 'i2c dev 2' commands because a bus can be probed using req_seq or seq interchangeably.
