The scope of the of_property command is limited to the internal devicetree
only. There is the possibility to add fixtures to postpone the operation
until boot and after the kernel DTB is already loaded, but this does not
cover the case when the property value needs to be phandle adresses

The gpio device nodes are subnodes of the pinctrl device node, so we can
register a regular driver for it. With this deep-probe support finds a
driver for the gpio device nodes and of_device_ensure_probed() can
correctly work on the gpio nodes.

The root node of the live tree should never be deleted, so refuse to do
so and print an error message. Deleting the live tree was possible with
the oftree -f command which was removed in c39c70bac5 ("commands: oftree:
kill oftree -f"). As this no longer exists we also do not need the
During deletion of device nodes of_find_device_by_node() is called in
order to set the device_node pointer of the device corresponding to
the to-be-deleted node to NULL. This is not necessary anymore as the
live tree should not be deleted.
This fixes problems with deep-probe support.

To make changes to the SDRAM controller effective, the APPLYCFG bit must
be set after programming the bitstream to the FPGA. This has to be done
without any SDRAM usage. Therefore copy the function to execute to the
OCRAM and execute it from there.

The pinctrl controller node is the first parent node that has a compatible
property. Use that information to find the node without iterating up to
the root node.

This is required for the new deep-probe mechanism. Barebox deep-probe
calls of_probe() very late and so clock drivers using the old
CLK_OF_DECLARE_DRIVER() mechanism are added very late. This would break
the deep-probe approach.
Move of_clk_init() and call it right before

With deep probe support the device providing the console can come quite
late in the probe order. Make sure it's probed at postconsole_initcall
time as it used to be without deep probe support so that we get output
earlier.

With deep probe support we decide that a device for a new device node is
available when the device has a driver. It sometimes happens that a
consumer of a device node doesn't point to the node to which the driver
is attached to, but instead a subnode, like this:

Instead of calling it from of_probe, convert it to a initcall at
the appropriate level. This allows to move of_probe to later in
the init sequence while keeping the memory init at the same place,
which is important as many other drivers need the valid memory area
to be set up
This adds deep probe support for pinctrl.
