We can remove the original sifive_plic_irqs_pending() function and
instead just use the sifive_plic_claim() function (renamed to
sifive_plic_claimed()) to determine if any interrupts are pending.
This requires move the side effects outside of sifive_plic_claimed(),
but as they are only invoked once that isn't a problem.
We have also removed all of the old #ifdef debugging logs, so let's
cleanup the last remaining debug function while we are here.
