This looks better and allows us to see the row and column numbers

+               MATRIX_KEY(0,  2, 0x39)

Can this also be switched over to using KEY_* macros to describe the
keycodes emitted?


That's going to be done in a follow up patch. This change here was
done mechanically, but moving to KEY_* might need to be double
checked by hand since some of these do not seem to map how one
would expect to the function on the keypad.

Thanks,
Andrew
