[PATCH] atlas_btns - add loadable kemap support

[Dmitry Torokhov]

Hi,

The following patch adds support for loadable keymaps to atlas_btns
driver. If anyone has this hardware I woudl appreciate if you could
test the patch.

I think the easiest way to test is with keyfuzz:

        http://0pointer.de/lennart/projects/keyfuzz/

This driver uses 0-15 range of "scancodes".

Thank you.
