Because the 98dx3236 and similar SoCs are switch chips with integrated
CPUs they use a reduced pin count for the SDRAM interface. As such
"full" with is 32-bits and "half" width is 16-bits (as opposed to 64/32
on the discrete SoC). Set the reduced-width property on the sdramc node
to indicate this.
