net: ipa: introduce a common microcontroller interrupt handler
The prototype for an IPA interrupt handler supplies the IPA interrupt ID, so it's possible to use a single function to handle any type of microcontroller interrupt. Introduce ipa_uc_interrupt_handler(), which calls the event or the response handler depending on the IRQ ID provided. Register the new function as the handler for both microcontroller IPA interrupt types. The called functions don't use their "irq_id" arguments, so remove them.
