Subject: [PATCH 1/7] KVM: x86: hyper-v: Mention SynDBG CPUID leaves in api.rst
We forgot to update KVM_GET_SUPPORTED_HV_CPUID's documentation in api.rst
when SynDBG leaves were added.
While on it, fix 'KVM_GET_SUPPORTED_CPUID' copy-paste error.
Fixes: f97f5a56f597 ("x86/kvm/hyper-v: Add support for synthetic debugger interface")
