svm: Fake out the Bus Unit Config MSR on revF AMD CPUs
Win2k8 x64 reads this MSR on revF chips, where it wasn't publically
available; it uses a magic constant in %rdi as a password, which we
don't have in rdmsr_safe(). Since we'll ignore the later writes, just
use a plausible value here (the reset value from rev10h chips) if the
real CPU didn't provide one.
