If the CSRs and CSR instructions are disabled because the Zicsr extension isn't enabled then we want to make sure we don't run any CSR instructions in the boot ROM. This patches removes the CSR instructions from the reset-vec if the extension isn't enabled. We replace the instruction with a NOP instead. Note that we don't do this for the SiFive U machine, as we are modelling the hardware in that case.
