On all other boards, we have the bus-width property in the board-specific
.dts instead of in the SoC-specific .dtsi.

I'd like us to be consistent as much as possible.
But I do wonder why it has been added as a board property.

I did see that.
But, in my opinion, using 4-bit SDHI is way more common that 1-bit SDHI.
So I figured I'd make 4-bit the 'default' by putting it in the dtsi, and if for some reason someone needed 1-bit, they could override it in the board .dts.

It doesn't really matter to me. If you want me to move it to the board dts it to keep it consistent, just let me know and I'll change it.
