reg->phys_hi and assigned->phys_hi are big endian but we do an extra byteswap anyway when copying reg->phys_hi to assigned->phys_hi. To make things slightly more messy, we also add a relocatable bit (b_n()) although in the right endianness.
This fixes endianness of assigned->phys_hi. This is unlikely to produce any visible difference though as we should end up there only in the case of PCI hotplug and even then I am not sure if (d->io_regions[i].addr == PCI_BAR_UNMAPPED) == true.
