It cannot be used - remember the discussion about pinmux? We elected
to disable I2C1 at present since you didn't like my nvidia,pinmux
binding for selecting which value to pass to funcmux. The fix is to
pass 1 instead of 0 for that port, but we have no clean way to specify
this.

Rather disable it than leave it enabled and not working.

Simon
