ebugging information to serial port.

Could we instead add a config option to set the default to SERCON UART
address like we do for the debug UART address?
Some boards have different UARTs for debug and user console, so I don't
think we want these to be mutually exclusive.
How about something

When tis_probe() returns '1', it means the interface was detected.
If all registers return 0x in the no-TPM case we should return a '0'
from tis_probe since rc was set to 0 from tis_wait_access() and we will not get
into the ifaceid test case. If they return 0 then we shouldn't get past

Thanks for putting this together.
