[PATCH] arm: dts: imx8mn-u-boot: fix DD3 only support

[Dario Binacchi]

In case the CONFIG_IMX8M_LPDDR4 and CONFIG_IMX8M_DDR4 options are both
disabled (i. e. BSH boards), binmain fails because DD4 bin files are
missing.

Fixes: 93c4c0e4dd1e75 ("arm: dts: imx8mn-u-boot: Create common imx8mn-u-boot.dtsi")
