Currently, the sbi_pmu_test continues if the exception type is illegal instruction because access to hpmcounter will generate that. However illegal instruction exception may occur due to the other reasons which should result in test assertion. Use the stval to decode the exact type of instructions and which csrs are being accessed if it is csr access instructions. Assert in all cases except if it is a csr access instructions that access valid PMU related registers. Take this opportunity to remove the CSR_CYCLEH reference as the test is compiled for RV64 only.
