KVM requires EVENTFD, which is selected by HAVE_KVM. Other KVM
supporting architectures select HAVE_KVM and then their KVM
Kconfigs ensure its there with a depends on HAVE_KVM. Make RISCV
consistent with that approach which fixes configs which have KVM
but not EVENTFD, as was discovered with a randconfig test.
