binman: Add support for passing arguments to entries

Sometimes it is useful to pass binman the value of an entry property from
the command line. For example some entries need access to files and it is
not always convenient to put these filenames in the image definition
(device tree).

Add a -a option which can be used like this:

-a<prop>=<value>

where

<prop> is the property to set
<value> is the value to set it to

dtoc: Drop use of a local dtb buffer

At present the Fdt class has its own copy of the device tree. This is
confusing an unnecessary now that pylibfdt has its own. Drop it and
provide access functions to the buffer.

This allows us to move the rest of the implementation to use pylibfdt
methods instead of directly calling libfdt stubs.

dtoc: Add some tests for the fdt module

At present this module is tested via the dtoc tests. This is a bit painful
since the tests are at a higher level and so failures are more difficult
to diagnose.

Add some tests that exercise the fdt module directly.
