Input: pmouse - move Sentelic probe down the list

Browse Source 
commit 4a18b3ab6e upstream.

Sentelic probes confuse IBM trackpoints so they stop responding to
TP_READ_ID command. See:

	http://bugzilla.kernel.org/show_bug.cgi?id=14970

Let's move FSP detection lower so it is probed after trackpoint and
others, just before we strat probing for Intellimouse Explorer.
