phy/core: move rd/wrcmdphase and computation to Multiplexer.
...
rd/wrcmdphases are always computated as (rd/wrphase-1)%nphases so it's not useful
to expose them as PhySettings. rd/wrcmdphases are now directly computated in
Multiplexer and static/dynamic rd/wrphases are supported.

phy/s7ddrphy: remove interface_type parameter and ISERDESE2's MEMORY_MODE support.

the behaviour.
