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.

phy/utils: improve ConstBitSlip:
...
* optional register=False to decrease latency by 1 cycle
* require explicit `cycles` as it influences latency (min_cycles
still can be used)
* add unit tests

lpddr4: implement ZQC through MPC and include it in init sequence
...
We do not yet support ZQC during operation (after init sequence)
as LPDDR4 requires 2-stage ZQC (start+latch) and 1us in between,
which requires modifying Refresher (ZQCExecutor) in LiteDRAM.
