abb.c & init.c: sync with Magnetite for Luna additions
These Luna target-specific additions are conditionalized on CONFIG_TARGET_LUNA,
a C preprocessor symbol that will never be defined in Selenite, hence this
change has exactly zero impact on FC Selenite. However, they are being pulled
in as a sync in order to keep the diff between Magnetite and Selenite to a
minimum; keeping this diff to a minimum increases our opportunities for
possible evolution of future FC firmwares.
