By default, TFM enables hardware rollback protection, which requires a
security counter to be embedded in the image trailer. The default
behaviour of constructing this counter from the image version breaks the
TFM `boot_nv_security_counter_update` implementation once the version
number is greater than `0.0.1024`. As such, explicitly specify the
desired security counter value. As per the MCUboot docs, this does not
need to be incremented on every firmware update.
