[PATCH v6 06/12] events/x86: Define SCI virtual interrupt

[Boris Ostrovsky <boris.ostrovsky@oracle.com>]

PVH guests do not have IOAPIC which typically generates an SCI. For
those guests SCI will be provided as a virtual interrupt.

Copy VIRQ_MCA definition from of xen-mca.h to xen.h to keep all
x86-specific VIRQ_ARCH_* in one place. (However, because we don't
want to require inclusion of xen.h in xen-mca.h we preserve original
definition of VIRQ_MCA as well.)
