cc bl: allow bootloader to force safe-boot into firmware

Browse Source 
This can be used by the GCS firmware uploader widget to boot
the firmware with a (temporarily) defaulted hwsettings uavo
so that a user can easily recover from a bad/incompatible
hwsettings configuration without wiping all settings.

This uses the same mechanism that the BootFault auto-recovery
code already uses in the CC firmware.  The auto-recovery is
triggered by setting the failed-boot counter to a maximum
value forcing recovery on the next FW init.
