KVM: SVM: Move global "avic" variable to avic.c

Browse source

Move "avic" to avic.c so that it's colocated with the other AVIC specific
globals and module params, and so that avic_hardware_setup() is a bit more
self-contained, e.g. similar to sev_hardware_setup().

Deliberately set enable_apicv in svm.c as it's already globally visible
(defined by kvm.ko, not by kvm-amd.ko), and to clearly capture the
dependency on enable_apicv being initialized (svm_hardware_setup() clears
several AVIC-specific hooks when enable_apicv is disabled).

Alternatively, clearing of the hooks (and enable_ipiv) could be moved to
avic_hardware_setup(), but that's not obviously better, e.g. it's helpful
to isolate the setting of enable_apicv when reading code from the generic
x86 side of the world.

No functional change intended.
