Immediate uses I could see would be replacing the PHB(DBG|INFO|ERR)
macros that do the PHB#%04x[%d:%d]: printing, the lock printing code,
the mbox-flash window printing code, and some of the FSP message logging
stuff.

We can probably end up unit testing this code too without *tooo* much
swearing.

Is cleaning it up/converting somewhere on the radar at all?
