Add method to turn off UCD90160 hardware accesses
As the fault monitoring functionality is going in toward
the end of a release, a flag is being provided to quickly
turn off the hardware accesses while still leaving the
ability to create general errors on PGOOD fails, as
well as issuing a shutdown on a runtime PGOOD fail.
This is meant to used if it turns out there are problems
with the hardware that end up taking a lot of time to debug.
The flag is --enable-turn-off-ucd90160-access.
