Just a thought.
pmd are pmc are cpu model specific. Although I'm not sure future model
will crease the number of them, It would be safe to keep pmd/pmc
separeted from vcpu_guest_context.

Anothor approach would be that only generic part of pmcs and pmds
(pmc0-7, pmd0-7 according to perfmon_generic.h) are included
in vcpu_guest_contest. Model specific part must be handled somehow anyway.
