Current implementation of SPMI arbiter dispatches interrupt based on
the Arbiter's accumulator status, in some cases the accumulator status
may remain zero and the interrupt remains un-handled. Add logic to
dispatch interrupts based Arbiter's IRQ status if the accumulator
status is zero.
Bug: 63899519
Test: Booted and ran modified code on walleye and taimen without any
apparent issues. Problem being addressed has no reliable repro method
and occurs very infrequently, so efficacy will be monitored via
population data.
