Convert alloc_dom0_vcpu0() to dom0_set_affinity(), making it only set up the

introduce alloc_dom_vcpu0() as the replacement for alloc_dom0_vcpu(). Then have
alloc_dom_vcpu0() call dom0_set_affinity() when the boot domain is the control
domain, otherwise set the affinity to auto.

Similar as before, this probably wants to be DOMAIN_CAPS_HARDWARE?
I'll adjust while rebasing.
Does it?
