dtoc: Support properties containing multiple phandle values
At present dtoc has a very simplistic view of phandles. It assumes that a property has only a single phandle with a single argument (i.e. two cells per property). This is not true in many cases. Enhance the implementation to scan all phandles in a property and to use the correct number of arguments (which can be 0, 1, 2 or more) when generating the C code. For the struct definitions, use a struct which can hold the maximum number of arguments used by the property.
