ubb-patgen/ubb-patgen.c: clean up pattern generation and boundaries
...
The main change is to use only a single transfer and thus avoid tri-stating
DATx during the command phase. To control the timing, we put the first word
"manually" into the FIFO, wait until it has been sent on the bus, and only
then DMA the rest.

ubb-patgen/: add DMA-based pattern transfer (WIP)
...
Works for some patterns but seems to have issues at the edge of
transfers. Clock selection also needs more work.
