Configure the 2 ranks. (init commands, leveling)
How to drive ODT?
Pipeline stall while switching ranks?

phy/s7ddrphy: simplify cmd/dat phases computation and remove restrictions.
...
The real restrictions are:
- dat_phase = sys_latency*nphases - cas_latency (at least for writes, for read we can compensate that with bitslip)
- dat_phase != cmd_phase.
