[PATCH 1/3] input: alps: Reset mouse before identifying it

[Pali RohÃr]

On some systems after starting computer function alps_identify() does not detect
dual ALPS touchpad+trackstick device correctly and detect only touchpad.

Resetting ALPS device before identifiying it fixing this problem and both parts
touchpad and trackstick are detected.
