[PATCH] Input: ALPS - Recognise "Dolphin V2" touchpads

This is the touchpad used on the Dell Vostro 3360. Without
this change, the driver reports this as follows:

psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 50, EC=73 02 02

It seems to use the ALPS V5 protocol, so identify it
as such by allowing ec[1] == 0x02.

This is based on src/alps.c from the DKMS driver here:
