report successful startup to the platform

For proper CCD password management it is necessary to be able to alert
the rest of the system when the actual restart happens. A good
indication of a restart is successful processing of the Starup command
of the SU_RESET type.

CQ-DEPEND=CL:804141
BRANCH=cr50
BUG=b:67007578
TEST=verified that the callback is indeed called on appropriate starups.
