firmware: fix TOCTTOU race in sync/async RPC code.
...
Before this commit, the main loop in session code was laid like:
1. process_kern_queued_rpc
2. process_host_message
3. process_kern_message
If a host message (such as an RPC reply) caused the kernel to exit,
then any async RPCs would not complete, since RunFinished immediately
shuts down the kernel.
Fix this by reordering 1 and 2.

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.
