The filename of the auto-generated file is the same as the file that
includes it. Even though the form is in the generated/ subdirectory, this
could be confused.

Rename the generated file to something that makes it clear it is
auto-generated.

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.

We want to support more than one phandle argument. It makes sense to use
an array for this rather than discrete struct members. Adjust the code to
support this. Rename the member to 'arg' instead of 'id'.

Rather than naming the phandle struct according to the number of cells it
uses (e.g. struct phandle_2_cell) name it according to the number of
arguments it has (e.g. struct phandle_1_arg). This is a more intuitive
naming.

The include-guard for dm-structs.h was misspelled as __DT_STTUCTS.
Change it.

This header can be included from anywhere, but will only pull in the
of-platdata struct definitions when this feature is enabled (and only in
SPL).
