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