[PATCH] Documentation: KVM: KVM_GET_SUPPORTED_CPUID now exposes TSC_DEADLINE

[Paolo Bonzini <pbonzini@redhat.com>]

TSC_DEADLINE is now advertised unconditionally by KVM_GET_SUPPORTED_CPUID,
since commit 9be4ec35d668 ("KVM: x86: Advertise TSC_DEADLINE_TIMER in
KVM_GET_SUPPORTED_CPUID", 2024-12-18).  Adjust the documentation to
reflect the new behavior.

+On newer versions, ``KVM_GET_SUPPORTED_CPUID`` does report the bit as available.
