common/keyboard_8042: Add ability to send/receive AUX data
* Added CHAN_AUX to CHAN enum.
* Added two new types to kblog for AUX data.
* Moved mouse methods to handle_mouse_data so they can respond on the
AUX channel.
* Call lpc_aux_put_char to put an AUX byte.
* Added send_aux_data_to_host and send_aux_data_to_device to pipe data in
and out of the 8042. CONFIG_8042_AUX must be set if the board
implements these methods.
BUG=b:145575366
BRANCH=none
TEST=Verified I can see AUX data going in and out.
