SECURE BOOT: Halt execution when secure boot fail
In case of fatal failure during secure boot execution (e.g. header
not found), reset is asserted to stop execution. If the RESET_REQ
is not tied to HRESET, this allows the execution to continue.
Add esbh_halt() after the reset to make sure execution stops.
