phy/usddrphy: simplify tCK reference by using a specific ODELAYE3 in FIXED mode and keep the PHY in reset by default.
...
Keeping the PHY in reset by default was not possible previously due to the ODELAYE3 configuration
that was lost on reset. Using a specific ODELAYE3 in FIXED mode allow keeping the PHY in reset at
startup.

...
Allow adding a delay on Clock/Commands. Delay is manual for now but could be
automated in the future if useful (as done on 7-series/Ultrascale(+)).

ecp5ddrphy: Fix DELAYF initial value
...
I've seen intermittent failures with recent builds. I suspect it is
related to the DELAYF primitive not being correctly loaded with an
initial value. Holding LOADN LOW ensures a value is correctly
loaded.
