board: solidrun: clearfog: enable ddr odt0 on write for both chip-select

Enabling ODT is required to suppress reflection of the data signal on
DDR write operation. SolidRun Armada 388 SoM only connects M_ODT[0] even
when both chip-select are used.

Enable ODT[0] for both chip-select during write only.
