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.
