RISC-V: KVM: Add ONE_REG interface to enable/disable SBI extensions

Browse source

We add ONE_REG interface to enable/disable SBI extensions (just
like the ONE_REG interface for ISA extensions). This allows KVM
user-space to decide the set of SBI extension enabled for a Guest
and by default all SBI extensions are enabled.
