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.

to expose them as PhySettings. rd/wrcmdphases are now directly computated in
Multiplexer and static/dynamic rd/wrphases are supported.
