Bootrom: Added an efuse_init "success" landmark
Bootrom: Added an efuse_init "success" landmark

Added an "efuse_init: OK" debug message to provide a static testing
landmark. Previously, one had to deduce the success by the presence of later
debug messages, which changed over time (e.g., once load-over-UniPro was
enabled).

Testing Done: verified that the string appears in success cases and not for failures.
Bug Number: trivial
