Commit 1b90d56e changed the implementation of in/out imm to not assign
the accessed port number to cpu_T[0] as it appeared unnecessary.
However, currently gen_check_io() makes use of cpu_T[0] to implement the
I/O bitmap checks, so it's in fact still used and the change broke the
check, leading to #GP in legitimate cases (and probably also allowing
access to ports that shouldn't be allowed).
This patch reintroduces the missing assignment for these cases.

As we will not have a cpu_x86_find_by_name() function anymore,
move the KVM default-vendor hack to instance_init.
Unfortunately we can't move that code to class_init because it depends
on KVM being initialized.

As eventually the x86_def_t data is going to be provided by the CPU
class, it's better to not touch it, and handle the special cases on the
X86CPU object itself.
Current behavior of the code should stay exactly the same.

The compiler is already able to eliminate the kvm_arch_get_supported_cpuid()
calls in kvm_cpu_fill_host() and filter_features_for_kvm(), so we can
eliminate the CONFIG_KVM #ifdefs there.
Also, kvm_cpu_fill_host() and host_cpuid() don't need to check
CONFIG_KVM, as they don't have any KVM-specific function calls.
Tested to build successfully with CONFIG_KVM disabled, using the
following CFLAGS combinations: "-DNDEBUG", "-DNDEBUG -O', "-DNDEBUG
-O0", "-DNDEBUG -O1", "-DNDEBUG -O2".

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.
And the MSRs are only there if the hypervisor has KVM_CAP_HYPERV.

There's no need to check CPU xlevel2 before calling
kvm_arch_get_supported_cpuid(s, 0xC0000001, 0, R_EDX), because:
* The kernel won't return any entry for 0xC0000000 if host CPU vendor
is not Centaur (See kvm_dev_ioctl_get_supported_cpuid() on the kernel
code)
* Similarly, the kernel won't return any entry for 0xC0000001 if
CPUID[0xC0000000].EAX is < 0xC0000001
* kvm_arch_get_supported_cpuid() will return 0 if no entry is returned
by the kernel for the requested leaf
For similar reasons, we can simply set x86_cpu_def->xlevel2 directly
instead of making it conditional, because it will be set to 0 CPU vendor
is not Centaur.
This will simplify the kvm_cpu_fill_host() code a little.
