[PATCH 1/5] risv: add missing SBI extension definitions

[Heinrich Schuchardt <xypron.glpk@gmx.de>]

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 for the sbi command. Remove
an #ifdef.

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