platform/x86: system76_acpi: Replace Fn+F2 function for OLED models
System76 laptops models with OLED displays do not support the default
Fn+F2 behavior of turning the embedded display on and off. Some models
instead introduce a new notify event that is used to lock the screen so
the OS will put the display in a low power state.
