ACPI: button: Pass ACPI handle to acpi_lid_evaluate_state()

Make it clear that acpi_lid_evaluate_state() only uses the ACPI handle
of the lid by changing its argument to acpi_handle and adjust its
callers accordingly.

Also save the ACPI handle of the lid, that later may be passed to
acpi_lid_evaluate_state(), in a static variable instead of saving a
pointer to the ACPI device object containing that handle.

No intentional functional impact.
