Enable battx_options for periphs if useful.
Enable the options parameter for the battery monitor on AP_Periph devices if they could be useful - ie, battery summing is enabled and in use on a node with more than one source for battery inputs.
Only define options in a single place
Single definition for non periph builds or if AP_BATTERY_SUM_ENABLED
we want the lua garbage collector to be used to re-use memory where
possible. This implements a suggestion from Thomas to avoid heap
expansion unless the last allocation failed
* remove unnecessary nullptr check, these are always called from an
initialized AP_DroneCAN so if it's nullptr something has gone
horrifically wrong
* pass in driver index instead of repeatedly calling function to get it
* simplify error handling; knowing exactly which allocation failed is not
super helpful and one failing likely means subsequent ones will too,
as it can only fail due to being out of memory
