- add a dedicated register stage for the CSR address that gets updated only if there is an actual CSR access operation (reduces switching activity)
- code cleanup
- revert package function cleanup (Quartus issues warnings if variables are initialized only at declaration)
Quartus is unhappy (issues warnings) if variables are initialized only at declaration
no switching activity at all on CSR address net if there is no explicit CSR access operation in progress
