Without the 'dirty' flag properties are not written back to the
devicetree when synced. This means that new properties copied over to a
node are not always written out.
Fix this and add a test.

This permits implementation of a simple templating system, where a node
can be reused as a base for others.
For now this adds new subnodes after any existing ones.

At present it is not possible to have arguments which include spaces.
Update the function to only split the args if the property is a single
string. This is a bit inconsistent, but might still be useful.

It is helpful to support a string or stringlist containing a list of
space-separated arguments, for example:
args = "-n fred", "-a", "123";
This resolves to the list:
-n fred -a 123
which can be passed to a program as arguments.
Add a helper to do the required processing.

At present if we see 'ranges' property (with no value) we assume it is a
boolean, as per the devicetree spec.
But another node may define 'ranges' with a value, forcing us to widen it
to an int array. At present this is not supported and causes an error.
Fix this and add some test cases.

With of-platdata-inst we want to set up a reference to each devices'
parent device, if there is one. If we find that the device has a parent
(i.e. is not a root node) but it is not in the list of devices being
written, then we cannot create the reference.
Report an error in this case, since it indicates that the parent node
is either missing a compatible string, is disabled, or perhaps does not
have any properties because it was not tagged for SPL.

This existing code assumes that a reg property is larger than one cell,
but this is not always the case. Fix this assumption.
Also if a node's parent is missing the #address-cells and #size-cells
properties we use 2 as a default for each. But this should not happen in
practice. More likely the properties were removed for SPL due to there
being no 'u-boot,dm-pre-reloc' property, or similar. Add a warning for
this as the failure can be very confusing.

Add a new test that adds a subnode alongside an existing one, as well as
adding properties to a subnode. This will expand to adding multiple
subnodes in future patches. Put a node after the one we are adding to so
we can check that things sync correctly.
The testAddNode() test should be in the TestNode class since it is a node
test, so move it.

Scan the aliases in the device tree to establish the number of devices
within each uclass, and the sequence number of each.

Instead of using a separate step for this processing, handle it while
scanning its associated driver. This allows us to drop the code coverage
exception in this case.
Note that only files containing drivers are scanned by dtoc, so aliases
declared in a file that doesn't hold a driver will not be noticed. It
would be confusing to put them anywhere other than in the driver that they
relate to, but update the documentation to say this explicitly, just in
case.

These have '_test' suffixes which are not present on the drivers in the
source code. Drop the suffixes to avoid a mismatch when scanning.

It is confusing to have the test files in the same places as the
implementation. Move them into a separate directory.
Add a helper function for test_dtoc, to avoid repeating the same
path.
