phy/lpddr5: delay WCK sync FSM transition by 1 cycle
...
With fixed serialization logic WCK sync can be now started later
which avoids the need for special logic when tWCKENL=0.

phy/lpddr4: fix edge case error with CommandsPipeline ignoring a command
...
Command was being ignored when it occurred on the last phase and
the next command would invalidate the first phase. Now it is fixed
and a regression test is included. A fix in ConstBitSlip has been added
due to wrong Verilog being generated with cycles=1, register=False.

* optional register=False to decrease latency by 1 cycle
* require explicit `cycles` as it influences latency (min_cycles
still can be used)
