of: let of_unflatten_dtb return the unflattened tree
...
In order to be able to handle multiple devicetrees, do not assume
the tree to be unflattened is the barebox internal one. Instead,
just return a pointer to it and assign the barebox internal root_node
external to the unflatten function.

highbank: use the provided dtb by the firmware to probe barebox device and mem size
...
the dtb is at 0x1000
if no dtb present use C code device
keep in C the timer/gpio/uart
have a nice tree
