I think it'd be be better to do this with the omap_register_i2c_bus()
call, since that's why the vector is provided with that call in the
first place.  It's one-stop shopping for setting up that bus:  mux the
pins, set up its default speed, register its devices.

Requiring two separate calls would be *less* clear.  And more error
prone ... shown by several patches preceding this one from Jarkko!!
