bootm: add initial FIT support ...

This implementation is inspired by U-Boot's FIT support. Instead of
using libfdt (which does not exist in barebox), configuration signatures
are verified by using a simplified DT parser based on barebox's own
code.

Currently, only signed configurations with hashed images are supported,
as the other variants are less useful for verified boot. Compatible FIT
images can be created using U-Boot's mkimage tool.

crypto: add digest_alloc_by_algo() ...

In barebox the function digest_alloc() allocates a digest based on a string.
When a subsystem already uses an integer value to identify a digest it makes no
sense to create a string and pass it to digest_alloc(), where it is parsed
again. This patch adds the possibility to get a digest by an enum.

OF: Fix fixups to fix Linux DT instead of Barebox DT ...

OF fixups cm_cogent_fixup() and hb_fixup() are supposed to modify the
Linux device tree.  And they did originally, but commit
e520a8c changed them to use
for_each_compatible_node(), which iterates through the Barebox DT.
Use new for_each_compatible_node_from() to specify the Linux DT root
as the start point.

socfpga: Find partition with environment via device tree ...

socfpga would load the environment from a file named "barebox.env"
located on the device "/dev/mmc0.1".  Both those names are hard-coded
in the socfpga code and can't be changed.

Barebox supports selecting the location of the environment using a
"barebox,environment" node in device tree's "chosen" node.  And
recently supports specifying that the env should come from a file on
this device.

Change socfpga to use this mechanism by adding the appropriate device
node.

cdev: When creating a new cdev, initialize device_node ...

If a new cdev doesn't have a device_node defined when passed to
devfs_create(), set it to the device_node of the parent device, if one
exists.

For non-partitions, like ocotp or eeprom devices, this is the correct
thing to do.  Partitions need to use, and do use, a different node.

The code from commit 274e0b8 to set
device_node in ocotp can be removed.

Add an extern declaration of socfpga_barebox_part to the socfpga
header so that a board can change it to use a different partition.

Initialize socfpga_barebox_part to the default value instead of NULL to
avoid the NULL check later.

bootstrap: Boot barebox with kernel calling convention ...

In commit 8e3ddc1 the bootm code was
changed to boot barebox using the same calling convention as the
kernel.  Which on ARM is to pass three arguments which are zero, an
architecture code, and a params pointer.

A 2nd stage barebox can be booted using lib/bootstrap, which is
different code from bootm.  This code just leaves garbage in the first
three parameters and so doesn't follow the convention.

Change it to be compatible with the ARM kernel booting convention.
This just sends a zero for the architecture, since the code for
architectures depends on boot[zmu] and something using bootstrap
wouldn't have those too.  And it just passes NULL for the params since
we don't have a way to pass a device tree from the preloader.

All users of bootstrap are ARM based, but the code is in lib so a
non-ARM board might someday make use of it.  If the current code would
work for them, then the change here will be ok too.
