phy/lpddr5/sim: partially disable DFITimingsChecker when --disable-delay is on
...
With --disable-delay the software won't insert delays in between
commands during memory training which results in DFITimingsChecker
reporting timing violations. With this change we disable
DFITimingsChecker until software completes memory initialization.
