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.

/*
 * These 7 branch instructions, corresponding to ARM exception and interrupt
 * vectors, will be placed in different sections depending on the flashImage
 * vs. ramImage configuration and which target we build for; this little
 * snippet file will be #included where it is needed.
