I think , only  esm at 40800000 should be good for this SOC.

I am not sure, why you want to add this. If you still want to add this 
for completeness ,

then two options, I suggest

1) If you plan to use this mention bootph-pre-ram and ti,esm-pins

2) In case , no plan to use this then please mark node as disabled
