Make POST codes written to IO port optional
This adds more configurability to POST codes. The current assumption
is that POST codes should be written to an IO port (e.g. LPC) if POST
codes are enabled. This changes the assumption so that POST codes can
be written to the serial console without being written to an IO port.
This enables POST codes by default using "default y" to avoid
changing current behavior.
