Well, I'm trying for staging merge at this point. Reasons why
gpio_matrix is there are:

1) it is non-trivial to remove

2) it has some features mainline lacks

3) HTC Dream actually works with it

(and 4) I'd like to submit code as Arve wrote it, then transform/clean
it up in staging).

Of course, relevant features will need to be extracted from
gpio_matrix and merged at the right places, and that needs to happen
before move from staging/, but I'd like to have working keyboard in
the meantime.
