[PATCH] arm: dts: imx8mn-beacon-kit-u-boot: Fix broken booting

[sbabic at denx.de]

> When the imx8mm.dtsi file was pulled in from Linux, the UARTs
> were moved into an spba sub-node which wasn't being included
> in the SPL device tree.  This meant the references to the UART
> weren't being handled properly and when booting the system would
