firewire: fw-ohci: disable PHY packet reception into AR context
We want the rcvPhyPkt bit in LinkControl off before we start using the chip. However, the spec says that the reset value of it is undefined. Hence switch it explicitly off. https://bugzilla.redhat.com/show_bug.cgi?id=244576#c48 shows that for example the nForce2 integrated FireWire controller seems to have it on by default.
