Hi Conor,

Thank you very much for taking care of this. Actually the PLIC may silently
ignore the enablement of interrupt 0, so the upstream openSBI won't notice
anything. My modified version, however, will deliberately trigger a fault
for all writes to the reserved fields of PLIC, thus catching this issue.

Hope it can clarify things a bit more.
