Thank you Masaki. I think we should not try to make
alps_set_abs_params_v7 also handle v8 down the road, but have separate
alps_set_abs_params_ss4_v2, so I changed this patch a bit, see below.
Thanks.

Input: ALPS - refactor alps_set_abs_params_mt()
From: Masaki Ota <masaki.ota@xxxxxxxxxxx>
In preparation for adding support for SS4 touchpads, let's split
alps_set_abs_params_mt into common, v7-specific, and other protocols
portions.
