new ABB_SLEEP_RESTRICTION definition in fc-target.h When we first introduced the mechanism to suppress ABB superdeep sleep on targets with LCDs powered from Iota VRIO, we made it conditional on CONFIG_TARGET_LUNA. This conditional is now being generalized: the feature in question is now conditionalized on the new ABB_SLEEP_RESTRICTION preprocessor symbol, to be defined in targets/*.h for those targets that need it. The new ABB_SLEEP_RESTRICTION definition is being added to targets/luna[12].h to keep the actual logic unchanged.
