[U-Boot] [PATCH 15/20] arm: rpi: Device tree modifications for U-Boot

Wed Jul 8 04:53:47 CEST 2015
This updates the device tree from the kernel version to something suitable
for U-Boot:
- Add stdout-path alias for console
- Mark the /soc node to be available pre-relocation so that the early serial
console works (we need the 'ranges' property to be available)
