SoC specific dtsi files that the boards can include. This lets us
remove:
CONFIG_SOC_PART_NUMBER_SAME70*

Underscore ('_') isn't a valid char for alias names based on the device
tree spec. Newer dtc compilers flag this as a warning so lets clean it

Move the dts files into the board dir so that board ports can be more
standalone. This will allow us at some point to have board ports
outside of the tree.
