sb/intel/lynxpoint: Ensure the finalise handler is called
The finalise handler is not called during S3 resume when using the `BS_PAYLOAD_BOOT` approach. So, adopt the `lpc_final` approach used by bd82x6x and others.
Tested on an ASRock H81M-HDS. The finalise handler is now called on the normal boot path, and during S3 resume.
