vfio-ccw: remove orb.c64 (64 bit data addresses) check
The vfio-ccw module does the check too, and there is actually no technical obstacle for supporting fmt 1 idaws. Let us be ready for the beautiful day when fmt 1 idaws become supported by the vfio-ccw kernel module. QEMU does not have to do a thing for that, except not insisting on this check.
