firewire: ohci: speed up PHY register accesses
Most PHY chips, when idle, can complete a register access in the time
needed for two or three PCI read transactions; bigger delays occur only
when data is currently being moved over the link/PHY interface. So if
we busy-wait a few times when waiting for the register access to finish,
it is likely that we can finish without having to sleep.
