Michał Żygowski 68ff33720a nb/intel/sandybridge/romstage.c: Configure DPR and initialize TXT
Initialize the DPR register and check if SCLEAN needs to be run.
Allows to reliably boot the platform if ungraceful shutdown occured or
the memory controller has been locked by TXT.

TEST=Dell OptiPlex 9010 with Intel TXT enabled boots successfully
after 4s power button override or power cable unplug when SENTER was
executed. Successfully boot QubesOS 4.0 with TBoot v1.8.2
