ACPI / button: Add quirks for initial lid state notification Linux userspace (systemd-logind) keeps on rechecking lid state when the lid state is closed. If it failed to update the lid state to open after boot/resume, the system suspending right after the boot/resume could be resulted. Graphics drivers also use the lid notifications to implment MODESET_ON_LID_OPEN option. Before the situation is improved from the userspace and from the graphics driver, users can simply configure ACPI button driver to send initial "open" lid state using button.lid_init_state=open to avoid such kind of issues. And our ultimate target should be making button.lid_init_state=ignore the default behavior. This patch implements the 2 options and keep the old behavior (button.lid_init_state=method).
