[PATCH] platform/x86/amd/pmc: Add PCSpecialist Lafite Pro V 14M to 8042 quirks list

[Mario Limonciello]

From: Mario Limonciello <mario.limonciello@amd.com>

Every other s2idle cycle fails to reach hardware sleep when keyboard
wakeup is enabled.  This appears to be an EC bug, but the vendor
refuses to fix it.

It was confirmed that turning off i8042 wakeup avoids ths issue
(albeit keyboard wakeup is disabled).  Take the lesser of two evils
and add it to the i8042 quirk list.

Thank you for your contribution, it has been applied to my local
review-ilpo-fixes branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my
local branch there, which might take a while.
