Do not set atcai2c.bus = 1 when bus is specified

[matsujirushi]

I want to use these scripts for Seeed reTerminal. ATECC608A is connected a Compute Module 4 via I2C bus 3.

Specifying a bus with the -p option does not work.

$ python3 ~/cryptoauthtools/python/examples/info.py -i i2c -p bus=3
Traceback (most recent call last):
  File "/home/pi/cryptoauthtools/python/examples/info.py", line 93, in <module>
    info(args.iface, args.device, **parse_interface_params(args.params))
  File "/home/pi/cryptoauthtools/python/examples/info.py", line 45, in info
    assert atcab_init(cfg) == ATCA_SUCCESS
AssertionError

This is a pull request that disables this logic when you specify bus with the -p option.
