Subject: [PATCH 2/2] Input: i8042 - Disable keyboard wakeup from s2idle on MSI Claw devices

On MSI Claw handheld gaming PCs, the volume buttons are considered a part
of an i8042 keyboard device and can wake the system from s2idle. This is
not expected behavior on a handheld gaming device, as the volume buttons
can easily be pressed while handling the device in its s2idle state.

To avoid this behavior, enable the SERIO_QUIRK_NOKBDWAKEUP quirk for all 
current MSI Claw models to disallow wakeup via the i8042 keyboard device
while maintaining volume button functionality.
