Subject: [PATCH] pms: minor cleanups in the alps code.

1. Update the ALPS_*_BEZEL values, which don't match the actual limits
accurately. The new values are used by Linux for all models with the
protocols "V1" and "V2".

2. Models with the ID 0x7331 are not supported properly, remove it
from the list.

3. Report to wsmouse that multiple contacts aren't recognized.
