[PATCH] Input: i8042 - add Dell XPS M1530 to nomux list

[Herton Ronaldo Krzesinski]

Dell XPS M1530 needs i8042.nomux=1 for ALPS touchpad to work as reported on
https://qa.mandriva.com/show_bug.cgi?id=43532

It is said that before A08 bios version this isn't needed (I don't have the
hardware so can't check), and suppose this will not break with bios versions
before A08.

I've got bios A08 (can't downgrade though). It works here, so:
