Depending on whether XIVE is emultated or backed with a KVM XIVE device, the ESB MMIOs of a XIVE source point to an I/O memory region or a mapped memory region. This is currently handled by checking kvm_irqchip_in_kernel() returns false in xive_source_realize(). This is a bit awkward as we usually need to do extra things when we're using the in-kernel backend, not less. But most important, we can do better: turn the existing "xive.esb" memory region into a plain container, introduce an "xive.esb-emulated" I/O subregion and rename the existing "xive.esb" subregion in the KVM code to "xive.esb-kvm". Since "xive.esb-kvm" is added with overlap and a higher priority, it prevails over "xive.esb-emulated" (ie. a guest using KVM XIVE will interact with "xive.esb-kvm" instead of the default "xive.esb-emulated" region. While here, consolidate the computation of the MMIO region size in a common helper.
