ACPI: button: Add DMI quirk for Samsung Galaxy Book2 to fix initial lid detection issue 



Add a DMI quirk for Samsung Galaxy Book2 to fix an initial lid state
detection issue.

The _LID device incorrectly returns the lid status as "closed" during
boot, causing the system to enter a suspend loop right after booting.

The quirk ensures that the correct lid state is reported initially,
preventing the system from immediately suspending after startup.  It
only addresses the initial lid state detection and ensures proper
system behavior upon boot.
