* When hitting EOL (end of list) at the data descriptor level, the DMA should mark the current context-descriptor as disabled and perform a context-store so software can see whats goin on.
* Context loads update RW_SAVED_DATA_BUF, data loads dont. This fixes an issue with ethernet bootstrapping.
* Reorder the logic for processing out channels to be more like the one for input channels.

Previous code assummed 32 by 32 bit divmod operation, and survived
x86_64 test only by sheer luck. MIPS wasn't so forgiving.

The IO index is now stored in its own field, instead of being wedged
into the vaddr field.  This eliminates the ROMD and watchpoint host
pointer weirdness.  The IO index space is expanded by 1 bit, and
several additional bits are made available in the TLB vaddr field.

Add basic support for TC6393XB system features. No support for GPIO
input though.
