OvmfPkg: QemuBootOrderLib: widen ParseUnitAddressHexList() to UINT64 

The OpenFirmware device path nodes that QEMU generates for virtio-mmio
transports contain 64-bit hexadecimal values (16 nibbles) -- the base
addresses of the register blocks. In order to parse them soon,
ParseUnitAddressHexList() must parse UINT64 values.

Call sites need to be adapted, as expected.
