32da475af1 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.

c6d036eaec Oops, use strtoul() instead of strtol() in dtc-lexer.l, so that we
correctly handle cell values above 7fffffff.  Bug pointed out by Kumar Gala.

c5c437e25b Oops. Using %{ %} in the rules (rather than definitions) section of a
lex file has undefined behaviour.  In fact it ends up including the stuff
within the definition of the yylex() function, leading to strange warnings
on gcc-3.4 and compile errors with gcc 4.
