* ams: replace sept with tsec firmware

This replaces sept with a custom tsec key derivation firmware.

NOTE: This does not use any TSEC exploits whatsoever; it is a well-signed
TSEC binary assembled with envyas and signed with the real cauth key.

For more details, contact SciresM#0524.

* fusee: only set SBK if it's readable
