DM: add deinit function for ps2kbd and ps2mouse

Browse Source 
Add deinit function for ps2kbd and ps2mouse.

To support deinit function for ps2kbd and ps2mouse which
has struct atkbdc_base as parameter, we make struct
atkbdc_base exported as public.

We also add console unregister function for keyboard
and mouse. Which are called in ps2mouse/ps2kbd deinit
function.
