logips2pp driver update (MX510/310 support), cleanup

[Eric Wong]

I've updated the logips2pp driver to detect the MX310 and MX510 mice
and also made it more maintainable by putting everything into one
table instead of having 4 arrays for them (the MX700 support wasn't
added correctly in the last revision).  Please apply.
