sb/intel/lynxpoint/lpc.c: Relocate lock bit write
This lock bit can be set later, and should also be set for LynxPoint-H.
This eases merging with Broadwell, which already sets this lock bit
after `spi_finalize_ops()` in a dedicated finalisation function.
Tested on Asrock B85M Pro4 (LynxPoint-H), the lock bit is now set.
