I'm mainly trying to remove irq_domain_remove_sim() and make it
possible to destroy the interrupt simulator domain with regular
irq_domain_remove(). If you prefer that we retain this routine as is,
I can limit this series to the first two patches, but I assumed the
fewer functions in the interface, the better. If you have a different
idea on how to do this - please let me know too.
