hw/intc/ibex_plic: Clear the claim register when read
After claiming the interrupt by reading the claim register we want to
clear the register to make sure the interrupt doesn't appear at the next
read.
This matches the documentation for the claim register as when an interrupt
is claimed by a target the relevant bit of IP is cleared (which we already
do): https://docs.opentitan.org/hw/ip/rv_plic/doc/index.html
This also matches the current hardware.
