Drivers usually need to re-apply the user-set IRQ affinity to their IRQs

for each IRQ, registering IRQ notifiers conflicts with the ARFS rmap
management in the core (which also registers separate IRQ affinity
notifiers).
Move the IRQ affinity management to the napi struct. This way we can have
a unified IRQ notifier to re-apply the user-set affinity and also manage
the ARFS rmaps. Patches 1 and 2 move the ARFS rmap management to CORE.
Patch 3 adds the IRQ affinity mask to napi_config and re-applies the mask
after reset. Patches 4-6 use the new API for bnxt, ice and idpf drivers.
Sorry for not-super-in-depth reviews, the patches didn't apply for me :(
But feels like we are pretty close.
No worries, I will rebase and send when net-next re-opens.
Thanks for the review.
