KVM: fix coexistence of KVM and Hyper-V leaves

kvm_arch_init_vcpu's initialization of the KVM leaves at 0x40000100
is broken, because KVM_CPUID_FEATURES is left at 0x40000001. Move
it to 0x40000101 if Hyper-V is enabled.

kvm: make availability of Hyper-V enlightenments dependent on KVM_CAP_HYPERV

The MS docs specify HV_X64_MSR_HYPERCALL as a mandatory interface,
thus we must provide the MSRs even if the user only specified
features that, like relaxed timing, in principle don't require them....

target-i386: kvm_cpu_fill_host(): Kill unused code

Those host_cpuid() calls are useless. They are leftovers from when the
old code using host_cpuid() was removed.

target-i386: kvm_cpu_fill_host(): No need to check level

There's no need to check level (CPUID0.EAX) before calling
kvm_arch_get_supported_cpuid(s, 0x7, 0, R_EBX), because:

  • The kernel won't return any entry for CPUID 7 if CPUID0.EAX is < 7
    on the host (See kvm_dev_ioctl_get_cpuid() on the kernel code);...

target-i386: kvm_cpu_fill_host(): No need to check CPU vendor

There's no need to check CPU vendor before calling
kvm_arch_get_supported_cpuid(s, 0xC0000000, 0, R_EAX), because:

  • The kernel won't return any entry for 0xC0000000 if host CPU vendor
    is not Centaur (See kvm_dev_ioctl_get_cpuid() on the kernel code);...

There's no need to check CPU xlevel2 before calling

target-i386: kvm_cpu_fill_host(): Set all feature words at end of function

Reorder the code so all the code that sets x86_cpu_def->features is at
the end of the function.

target-i386: kvm_cpu_fill_host(): Fill feature words in a loop

Now that the kvm_cpu_fill_host() code is simplified, we can simply set

target-i386: kvm_check_features_against_host(): Kill feature word array

We don't need the ft[] array on kvm_check_features_against_host()
anymore, as we can simply use the feature_word_info[] array, that has
everything we need.
