riscv: add missing SBI extension definitions

Add the System Reset Extension and the Hart State Management Extension
definitions.

Add missing RFENCE Extension enum values.

The SBI 0.1 extension constants are needed for the sbi command. Remove
an #ifdef.

Cf. https://github.com/riscv/riscv-sbi-doc/blob/master/riscv-sbi.adoc
