XHCI console works fine with UEFI boot, as Xen doesn't relocate itself. But on legacy boot, relocation is a problem, as the hardware is programmed with physical addresses of structures that are moved. Fix this by adding new console init hooks. This series includes also few minor improvements that were useful when working on the fix.
