Added privilege level check to ebreak with dcsr.ebreakm
Created by: silabs-oysteink
Added privilege level check to ebreak with dcsr.ebreakm. Will get optimized away during synthesis, but aligns code better with cv32e40s.
Small update to mtvec_mode_clic_resolve function which causes warnings on bit widths.
SEC clean
