(c) TNF line from 4-clause UCB to 3-clause UCB license; in other words, remove UCB's ad clause from the license TNF grants. There is no point in TNF demanding that UCB's ad clause be followed when even UCB doesn't demand it any longer. Ok'd by board@ and agc@.

/* Important! The 3 most significant bits of this register, in initiator mode,

|
* phase mismatch the chip will not transfer any data! This is actually a nice
|
|
* feature as it gives us a bit more control over what is happening when we are
|
|
* bursting data (in) through the FIFOs and the phase suddenly changes from
|
|
* DATA IN to STATUS or MESSAGE IN. The transfer will stop and wait for the
|
|
* proper phase to be set in this register instead of dumping the bits into the
|
|
* FIFOs.
