Input: i8042 - reset keyboard controller wehen resuming from S2R

Some laptops, such as Lenovo 3000 N100, require keyboard controller reset
in order to have touchpad operable after suspend to RAM. Even if box does
not need the reset it should be safe to do so, so instead of chasing
after misbehaving boxes and grow DMI tables, let's reset the controller
unconditionally.
