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.
