sb/intel/common: Create a common PCH finalise implementation
The common finalise code is used by bd82x6x, Lynx Point, and Ibex Peak.
Lynx Point now benefits from being able to write-protect the flash chip.
For Lynx Point, writing the SPI OPMENU now happens in ramstage, as done
in bd82x6x.
Tested on an ASRock H81M-HDS (Lynx Point). When write-protection is
configured, flashrom reports all flash regions as read-only, and does
not manage to alter the contents of the flash chip.
Also tested on an ASUS P8H61-M LX (Cougar Point). Everything seems to
work as before.
