Subject: [PATCH 2/5] Input: ALPS - add protocol version field in
 alps_model_info

In preparation for adding support for more ALPS protocol versions,
add a field for the protocol version to the model info instead of
using a field in the flags. OLDPROTO and !OLDPROTO are now called
version 1 and version 2, repsectively.
