Theoretically yes, but there are two reasons not to do that:
1) When Fadil Berisha chose the labels he didn't do so arbitrarily. The
   labels make sense the way the pinmux table is organised in the datasheet.
   (otherwise he sure would have chosen "i2c_pins_a" for the default pin
   group on olinuxino).
2) The labels are in use for about two years now by a lot of people. (Yes
   it really takes that long to have this merged.) I would hate to break
   their setups for no strong reason.
