platform/x86: ideapad-laptop: Only toggle ps2 aux port on/off on select models
Recently there have been multiple patches to disable the ideapad-laptop's
touchpad control code, because it is causing issues on various laptops:
Commit d69cd7eea93e ("platform/x86: ideapad-laptop: Disable touchpad_switch for ELAN0634")
Commit a231224a601c ("platform/x86: ideapad-laptop: Disable touchpad_switch")
The turning on/off of the ps2 aux port was added specifically for
the IdeaPad Z570, where the EC does toggle the touchpad on/off LED and
toggles the value returned by reading VPCCMD_R_TOUCHPAD, but it does not
actually turn on/off the touchpad.
The ideapad-laptop code really should not be messing with the i8042
controller on all devices just for this special case.
Add a new ctrl_ps2_aux_port flag set based on a DMI based allow-list
for devices which need this workaround, populating it with just
the Ideapad Z570 for now.
This also adds a module parameter so that this behavior can easily
be enabled on other models which may need it.
