Add logic to assign property values to nodes as required by dtoc. The
references allow nodes to refer to each other in C code. The macros used
by dtoc are not yet defined in driver model. They will be added along
with the actual driver model implementation.

Drivers can have private / platform data contained in structs and these
struct definitions are generally kept in header files. In order to
generate build-time devices, dtoc needs to generate code that declares
the data contained in those structs. This generated code must include the
relevant header file, to avoid a build error.
We need a way for dtoc to scan header files for struct definitions. Then,
when it wants to generate code that uses a struct, it can make sure it
includes the correct header file, first.
Add a parser for struct information, similar to drivers. Keep a dict of
the structs that were found.

Uclasses can have per-device private / platform data so dtoc needs to
scan these drivers. This allows it to find out the size of this data so
it can be allocated a build time.
Add a parser for uclass information, similar to drivers. Keep a dict of
the uclasses that were found.

In order to output variables to hold the priv/plat information used by
each device, dtoc needs to know the struct for each. With this, it can
declare this at build time:
u8 xxx_priv [sizeof(struct <name>)];
Collect the various struct names from the drivers.

We should ignore anything in the .git directory or any of the
build-sandbox, etc. directories created by 'make check'. These can confuse
dtoc. Update the code to ignore these.

At present we simply record the name of a driver parsed from its
implementation file. We also need to get the uclass and a few other
things so we can instantiate devices at build time. Add support for
collecting this information. This requires parsing each driver file.

Move the tests related to scanning into their own class, updating them
to avoid using dtb_platdata as a pass-through.

Before expanding the scanning features any more, move this into a separate
file. This will make it easier to maintain in the future. In particular,
it reduces the size of dtb_platdata.py and allows us to add tests
specifically for scanning, without going through that file.
The pieces moved are the Driver class, the scanning code and the various
naming functions, since they mostly depend on the scanning results.
So far there is are no separate tests for src_scan. These will be added
as new functionality appears.
This introduces no functional change.
