Subject: nb/intel/pineview: Move the boilerplate mainboard_romstage_entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The mainboard_romstage_entry function is mostly boilerplate, so move
it to a common location and provide mainboard specific callbacks.
