IB/hfi1: Rework the IRQ API to be more flexible
The current IRQ API is an all or nothing interface. This has two
problems:
1. All IRQs are enabled regardless of use
2. Moving from general interrupt to MSIx handling is difficult
Introduce a new API to enable/disable specific IRQs or a range of IRQs.
Do not enable and disable all IRQs in one step.
Rework various modules to enable/disable IRQs when needed.
