Subject: Input: i8042 - add HP Pavilion dv4s to 'notimeout' and 'nomux'
 blacklists

Touchpad input doesn't work with newer HP Pavilion dv4 laptops due to bad i8042
timeout data.  Booting with i8042.notimeout and i8042.nomux successfully works
around the problem.

This patch adds the devices to the i8042 notimeout and nomux blacklists.
