ad9910: rewire io_delay tuning
...
This now reliably locates the SYNC_CLK-IO_UPDATE edge by doing two
scans at different delays between start and stop IO_UPDATE.
It also works well when one delay is very close to the edge.
And it correctly identifies which (start or stop) pulse hit or crossed
the SYNC_CLK edge.

* moved continuous/relative phase offset tracking from an instance
variable to a "handle" returned by set()/set_mu() in order to avoid
state inconsistency with DMA (#1113 #1115 )
