The upstream (Linux) 'compatible' string for the Terasic
DE0-Nano-SoC/Atlas-SoC board in
"dts/src/arm/socfpga_cyclone5_de0_nano_soc.dts" differs from the barebox
'compatible' string for the same board in
"arch/arm/dts/socfpga_cyclone5_de0_nano_soc.dts":
Linux: "terasic,de0-atlas"
barebox: "terasic,de0-nano-soc"
That results in an incompatibility when trying to boot a bootloader spec
entry with a 'devicetree' key that refers to the DTB file built from the
Linux sources. The barebox bootloader spec loader will ignore the entry
because the 'compatible' string in the root node of the DTB does not
match what barebox expects.
Remove the 'compatible' string list from
"arch/arm/dts/socfpga_cyclone5_de0_nano_soc.dts" so that barebox uses
the upstream compatible string list. Also remove the 'model' string
("Terasic DE0-Nano-SoC/Atlas-SoC Kit") so that barebox uses the upstream
(and shorter!) model name ("Terasic DE-0(Atlas)").
Finally, update the `of_machine_is_compatible("terasic,de0-nano-soc")`
function call in `socfpga_init()` to use the "terasic,de0-atlas" string.

The phandles are unreferenced anywhere. They are likely a remnant of
copy and paste from another device tree that makes use of them, e.g. the
socfpga_cyclone5_socrates.dts. Drop them.

The environment nodes do not have a reg property and as such should not
have a @0 suffix. Newer dtc warns about this, so remove it.

Currently all upstream boards use the same barebox-environment setup.
It is however problematic to add new boards, that have a different setup.
Instead of having to /delete-node/ the file-path property in those boards,
move the environment to the specific board files.
This also has the charme of - maybe one day - getting rid of a barebox-version
of socfpga.dtsi :-)

v7: eof whitespace fixes
A Patch for supporting the Terasic DE0 NANO-SoC with barebox.
The pretty similar Socrates Board was taken as a starting point with pulling
in the memory timings/pinmux from
