Eclipse Webmaster requested to merge github/fork/silabs-oysteink/minhv_fix-1 into master Oct 26, 2022

Created by: silabs-oysteink

Updated handling of mret related to mcause.mpp and mcause.minhv. No inhv assumes for mpp==PRIV_LVL_U. Unique case violation in cs_registers due to clearing of minhv fixed, assertions added to make sure there is no conflicting writes to mcause.

When merged, this PR will be cherry picked to the E40X to apply the changes there. Should fix issue #498 on CV32E40X when done.
