[U-Boot] [PATCH 6/9] fdt: adjust bcm283x device tree for u-boot

[Fabian Vogt]

The information currently set via platdata has to be represented in the
device tree now. bcm283x-uboot.dtsi adds the u-boot specific "skip-init"
property to the serial nodes and enables initialization in the pre-reloc phase.
