Some functions have the same code in the subclasses. Move these into the
superclass to avoid duplication.

These functions are identical in both subclasses. Move them into the base
class.
Note: In fact there is a bug in one version, which was fixed by this patch:

These functions are currently in a separate fdt_util file. Since they are
only used from PropBase and subclasses, it makes sense for them to be in the
PropBase class.
Move these functions into fdt.py along with the list of types.

At present we have two separate implementations of the Fdt library, one which
uses fdtget/fdtput and one which uses libfdt (via swig).
Before adding more functionality it makes sense to create a base class for
these. This will allow common functions to be shared, and make the Fdt API
a little clearer.
Create a new fdt.py file with the base class, and adjust fdt_normal.py and
fdt_fallback.py to use it.

In preparation for creating an Fdt base class, rename this file to indicate
it is the normal Fdt implementation.

Add a Python version of the libfdt library which contains enough features to
support the dtoc tool. This is only a very bare-bones implementation. It
requires the 'swig' to build.
