This series adds support for the Smstateen specification which provides
a mechanism to plug potential covert channels which are opened by extensions
which add to processor state that may not get context-switched. Currently
access to AIA registers and *envcfg registers is controlled via
smstateen.
Changes in v2:
- Rebase on latest master branch
- Fix RV32 compilation issue
- Fix indentation issue
