In some cases it is useful to generate a FIT which has a number of DTB
images, selectable by configuration. Add support for this in binman,
using a simple iterator and string substitution.

If an entry argument is needed by an entry but the entry argument is not
present, then a strange error can occur when trying to read the file.
Fix this by allowing arguments to be required. Select this option for the
cros-ec-rw entry. If a filename is provided in the node, allow that to be
used.
Also tidy up a few related tests to make the error string easier to find,
and fully ignore unused return values.

At present we look for resources based on the path of the Python module
that wants them. Instead we should use Python's pkg_resources feature
which is designed for this purpose.

When reading subentries of each image, the FIT entry type directly
concatenates their contents without padding them according to their
offset, size, align, align-size, align-end, pad-before, pad-after
properties.
This patch makes sure these properties are respected by offloading this
image-data building to the section etype, where each subnode of the
"images" node is processed as a section. Alignments and offsets are
respective to the beginning of each image. For example, the following
fragment can end up having "u-boot-spl" start at 0x88 within the final
FIT binary, while "u-boot" would then end up starting at e.g. 0x20088.
fit {
description = "example";
images {
kernel-1 {
description = "U-Boot with SPL";
type = "kernel";
arch = "arm64";
os = "linux";
compression = "none";
u-boot-spl {
};
u-boot {
align = <0x10000>;
};
};
};
}

Other relevant properties (pad-after, offset, size, align, align-size,
align-end) already work since Pack() sets correct ranges for subentries'
data (.offset, .size variables), but some padding here is necessary to
align the data within this range to match the pad-before property.

When binman is installed its main program is in a different directory
to its modules. This means that __file__ is different and we cannot use

At present testPackX86RomMeNoDesc removes the contents of the

completely.
If a test that relies on this file happens to run after it is removed, it
will not work. Since we have no control over the selecting of tests that
run in parallel and series, we must avoid changing the files.

FIT (Flat Image Tree) is the main image format used by U-Boot. In some
cases scripts are used to create FITs within the U-Boot build system. This
is not ideal for various reasons:
- Each architecture has its own slightly different script
- There are no tests
- Some are written in shell, some in Python
To help address this, add support for FIT generation to binman. This works
by putting the FIT source directly in the binman definition, with the
ability to adjust parameters, etc. The contents of each FIT image come
from sub-entries of the image, as is normal with binman.
