Normally, for devices support MSI-X, PBA is passed-through to guest. However, PBA and MSI-X table share the same bar, and part of PBA and MSI-X table may share a same page for some devices. If that is the case, the part of PBA within the page should be emulated rather than passed-through. This patch adds PBA emulation support for MSI-X.
