board: kobol: helios4: 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.
See also commit d09f199097d3 ("board: solidrun: clearfog: enable ddr odt0
on write for both chip-select") where this was added to SolidRun
Clearfog board which is using the same System on Module but unlike
Helios-4 without ECC memory.
