KVM: x86/cpuid: generalize kvm_update_kvm_cpuid_base() and also capture limit

Browse source

A subsequent patch will need to acquire the CPUID leaf range for emulated
Xen so explicitly pass the signature of the hypervisor we're interested in
to the new function. Also introduce a new kvm_hypervisor_cpuid structure
so we can neatly store both the base and limit leaf indices.
