[v2,0/6] RISC-V: KVM: Make SBI uapi consistent with ISA uapi

Message

SBI extension UAPI is currently almost the same as the ISA extension
UAPI. This series closes the remaining gap by ensuring when an SBI
extension is not available that its register returns ENOENT when
accessed by userspace. We also drop the SBI multi registers from
get-reg-list (ISA multi registers aren't there either) and make
several improvements to the get-reg-list kselftest.

This series is based on Anup's riscv_kvm_more_exts_v1 branch.

Based on kvm-riscv/riscv_kvm_queue

v2:
 - Rebased on kvm-riscv/riscv_kvm_queue which is based on v6.7-rc5

Thanks,
drew
