Subject: [PATCH net-next 5/6] net: ipa: kill ipa_interrupt_add()
The dynamic assignment of IPA interrupt handlers isn't needed; we
only handle three IPA interrupt types, and their handler functions
are now assigned directly. We can get rid of ipa_interrupt_add()
and ipa_interrupt_remove() now, because they serve no purpose.
