Summary

Unfortunately there isn't any architecture-independent interrupt counter
access or initialization. Due to this, add yet another hook to all the
architecture to setup the counter.

I'm really unsure about this. There needs to be a solution to the issue of intrcnt_add() being x86-only, but I don't know whether the implementation in D31064 is appropriate (works as a stop-gap, but...).
