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.

i8042 controller present in Dell Vostro V13 errorneously signals spurious
timeouts.

Introduce i8042.notimeout parameter for ignoring i8042-signalled timeouts
and apply this quirk automatically for Dell Vostro V13, based on DMI match.

In addition to that, this machine also needs to be added to nomux blacklist.

The Sony VPCZ1 doesn't support active multiplexing and trying to enable
it causes keyboard to stop working. Since most (all?) VAIOs do not have
external PS/2 ports nor they implement active multiplexing properly, and
trying to enable MUX usually messes up keyboard/touchpad, let's simply
disable MUX probing based on board name (VAIO).

On this model, when KBD is in active multiplexing mode, acknowledgements
to reset and get ID commands issued on KBD port sometimes are delivered
to AUX3 port (touchpad) which messes up device detection. Legacy KBC
mode works fine and since there are no external PS/2 ports on this laptop
and no support for docking station we can safely disable active MUX mode.

It seems that many laptops do not fully implement AUX LOOP command in
their keyboard controllers, causing issues with touchpad detection.
We know however that almost every laptop/portable uses a PS/2 pointing
device and, even if user disables it in favor of an external mouse,
the system will not use IRQ 12 for anything else. Therefore we may
bypass AUX IRQ delivery test when running on a laptop and assume that
it is routed properly.

Just to be safe we require the box to have good PNP data in order to
bypass the test.
