sb/intel/lynxpoint: Make the finalise handler common

The ASRock H81M-HDS doesn't implement a finalise handler. To fix
this, and reduce code duplication in the process, make a common
implementation. There should be no functional change to boards with
existing finalise handlers, since the code is identical among them and
the new, common implementation.

Tested on an ASRock H81M-HDS. The finalise handler works.
