cr50: provide chip factory mode support
When in factory mode, we should not be trying to figure out board
strapping options, just enable SPI interface so that the tester can
communicate with the chip.
Also, to close the loop with the tester, let's add indication of the
cert installation result, by setting the two top bits of the DUMMY
(aka underrun) character to 1 and the lower bits to the endorsement
operation result (0 means success, nonzero values communicate
different failure modes) and by preventing the TPM driver from sending
anything but underrun chars on the SPI interface.
BRANCH=cr50
