Currently TYPE_XICS_BASE and TYPE_XICS_SIMPLE have their own reset methods,
using the standard technique for having the subtype call the supertype's
methods before doing its own thing.
But TYPE_XICS_SIMPLE is the only subtype of TYPE_XICS_BASE ever
instantiated, so there's no point having the split here. Merge them
together into just an ics_reset() function.
