Input: i8042 - also perform controller reset when suspending

commit 1729ad1f4f9e167ade84ca8b5269695c42351160 upstream.

In addition to some laptops needing i8042 reset after resuming from S2R to
get their touchpads working there is another class of laptops - ones that
need i8042 reset before going to S2R, otherwise they will simply reboot
instead of resuming.

See https://bugzilla.kernel.org/show_bug.cgi?id=15612

This change forces reset of i8042 before doing S2R.
