[Aaron Ma]

There is a regression of commit 4a646580f793 ("Input: ALPS - fix
two-finger scroll breakage"), ALPS device fails with log:

psmouse serio1: alps: Rejected trackstick packet from non DualPoint device

ALPS device with id "74 03 28" report OTP[0] data 0xCE after
commit 4a646580f793, after restore the OTP reading order,
it becomes to 0x10 as before and reports the right flag.
