First of all, we only need this EPT identity and TSS reservation on
Intel CPUs.

kvm-amd will ignore it just fine. I'd like to keep arch differences away from userspace.

Then, in order to support loading BIOSes>  256K, reorder the
code, adjusting the base if the kernel supports moving the identity map.
We can drop the check for KVM_CAP_SET_TSS_ADDR as we already depend on
much newer features.

There is no ordering on kvm features.  Each can come and go as it pleases.
