Add U-Boot override for RB1 to for USB in host mode as OTG mode isn't
supported. Also, disable sdhc_2 as it's currently not supported, sdhc_1
works fine though.

I'd rather avoid disabling this here, I guess it's just missing clocks and regulators which doesn't justify modifying DT. An error that mmc1 couldn't be enabled seems fine to me?> +&sdhc_2 {
