of: Use correct devicetree in of_print_cmdline ...

of_print_cmdline() is passed a devicetree, so use this one instead
of the internal devicetree. This fixes the cmdline printout when
bootm on ARM is used with an external devicetree.

Being able to trace initcall is very useful when trying to

it to make it easier to access.

add function to get boardinfo string ...

When using devicetrees the boardinfo (or model) can be obtained
from the devicetree. Add a function to get the boardinfo so that
we have a chance to add information from the devicetree.

remove unused debug Kconfig options ...

ENABLE_DEVICE_NOISE is used only in two network drivers and is
otherwise unused. ENABLE_FLASH_NOISE is completely unused.
ENABLE_PARTITION_NOISE enables DEBUG in the partition command,
but this code has no debug messages at all.

Remove all this.

OF: base: sync of_find_node_by_path with linux OF API ...

Barebox of_find_node_by_path requires a node to be passed as start node
to start searching. Linux OF API does not pass this node and no current
user of it in barebox is passing anything else than the root node.
Therefore, we rename current function to of_find_node_by_path_from and
introduce a Linux OF API compatible of_find_node_by_path that always
passes the current root_node. Also, all current users of that function
are updated to reflect the API change.
