sayma: rework DAC SYSREF margin validation
...
Previous code did not work when delay range was not enough for two rotations.
This removes autocalibration, to be done later. Uses hardcoded value for now.

firmware: implement DDMTD-based SYSREF/RTIO alignment (draft)
...
Mostly works and usually gets the DAC synchronized at 2.4GHz with Urukul across DRTIO.
Needs cleanup and optimization/characterization.

sayma: SYSREF setup/hold validation demonstration
...
This also removes the standalone target as the ISERDES used
for setup/hold check requires the fine RTIO clock, which in turn
requires a DRTIO transceiver due to the Ultrascale TPWS bug.

* gets another clock divider out of the way
* gets one cycle within range of the HMC7043 analog delay alone
* SYSREF/RTIO alignment removed, to be replaced with DDMTD-based scheme

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.

firmware: Use larger ARP cache
...
This works around a problematic interaction between ARP cache
expiry in smoltcp (with its 3 seconds timeout before a discovery
request is sent) and our TCP keepalive settings, where the timeout
is reached before the keepalive had a chance to be sent.
GitHub: Closes #1150 .
