According to the TRMs of K3 platform of devices, the ROM boot image
format specifies a "Core Options Field" that provides the capability to
set the boot core in lockstep when set to 0 or to split mode when set
to 2. Add support for providing the same from the binman DTS. Also
modify existing test case for ensuring future coverage.

Do you think there could be a binding file in dt-bindings/ for this value?
Sorry for getting back to this patch so late, but wanted to ask about this. I
had seen a last version of getting the binman compatible in dt-bindings but I
don't see it merged. Not sure where I would add this property in.
