Re: [dtc] Allow multipart property values

So, like, the other day David Gibson mumbled:

There's nothing in tests/ though - I always meant to make a testsuite,
but I never got around to it.  Current plan is to implement a
testsuite by merging libfdt into the dtc tree.

Here's a revised patch which adds an example usage to test.dts

[dtc] Allow multipart property values

At present each property definition in a dts file must give as the
value either a string ("abc..."), a bytestring ([12abcd...]) or a cell
list (<1 2 3 ...>).  This patch allows a property value to be given as
several of these, comma-separated.  The final property value is just
the components appended together.  So a property could have a list of
cells followed by a string, or a bytestring followed by some cells.
Cells are always aligned, so if cells are given following a string or
bytestring which is not a multiple of 4 bytes long, zero bytes are
inserted to align the following cells.

The primary motivation for this feature, however, is to allow defining
a property as a list of several strings.  This is what's needed for
defining OF 'compatible' properties, and is less ugly and fiddly than
using embedded \0s in the strings.

Applied.
