After a claim or a priority change we need to update the pending
interrupts. This is based on the same patch for the SiFive PLIC:
5576582280 "riscv: plic: Add a couple of mising
sifive_plic_update calls"

The Ibex core contains a PLIC that although similar to the RISC-V spec
is not RISC-V spec compliant.
This patch implements a Ibex PLIC in a somewhat generic way.
As the current RISC-V PLIC needs tidying up, my hope is that as the Ibex
PLIC move towards spec compliance this PLIC implementation can be
updated until it can replace the current PLIC.
