Update CSR Yaml

Created by: silabs-robin

This PR updates the CSR Yaml definitions.

Steps done:

• Base off design's local Yaml definition
• Merge with Henrik's tentative Yaml definition
• Run cv32e40s_csr_access_test and update definition according to test failures
• Run cv32e40s_csr_access_test with ISS and fix mismatches

When generating C macros, different conditionals can be applied with a script in core-v-verif to match different parameter sets.

Review and feedback wanted. @Silabs-ArjanB, @silabs-oysteink, @silabs-oivind, @silabs-hfegran, if any of you would be willing.
