Log Message:
Sync with the following OpenBSD changes, but do the shared interrupt
reporting differently.  Each cpu and device interrupt gets its own
counter.

revision 1.14
Fix counting of interrupts for devices that attach to elroy(4).  Shared
interrupts would be counted double, once for the interrupting device and
once for the device at the head of the chain.  The handlers would run properly
though.  Avoid this by giving each device its own interrupt counter instead
of using the counter provided by the generic interrupt handling code for the
head of the chain.

revision 1.13
Stop calling shared interrupt handlers as soon as one of them return 1
(positive interrupt was for me), like we do on other architectures.
This is done here, at the elroy(4) driver level, since this is where shared
PCI interrupts are handled.  We could do something similar for dino(4) but
this optimization is probably not very relevant there.
