sayma_rtm_drtio: use Si5324 soft reset
...
Needs easy board rework to cut trace at pin 1 of Si5324.
The Si5324 contains an internal pull-up on that pin.
Allows using Si5324 + HMC7043 chips at the same time.
Allows the Si5324 bypass hack for DDMTD experiments on the RTM.

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.

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.
