[RFC PATCH v1 0/3] RISC-V Smstateen support

[Mayuresh Chitale]

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.
