Update alu operands (csr address) for CSR instructions; not sec clean
Created by: Silabs-ArjanB
Temporary change to allow for a following SEC clean divider related update. Not SEC clean. This fix is related to csr_en not being suppressed for killed instructions (an issue will be filed to get that fixed). Signed-off-by: Arjan Bink Arjan.Bink@silabs.com
