fdt: fix dts preprocessor options

Using "-ansi" preprocessor option will cause dts lines that begin with
'#' to choke the preprocessor.  Change to "-x assembler-with-cpp"
instead which is what the kernel uses to preprocess dts files.

treewide: include libfdt_env.h before fdt.h

and, if including libfdt.h which includes libfdt_env.h in
the correct order, don't include fdt.h before libfdt.h.

this is needed to get the fdt type definitions set from
the project environment before fdt.h uses them.

common/fdt_support.c: sparse fixes

trivial:

fdt_support.c:325:65: warning: Using plain integer as NULL pointer
fdt_support.c:352:65: warning: Using plain integer as NULL pointer

For the following bad constant expression, We hardcode the max. number of
memory banks to four for the foreseeable future, and add an error with
instructions on what to do once it's exceeded:

fdt_support.c:397:22: error: bad constant expression

For the rest below, sparse found a couple of wrong endian conversions
in of_bus_default_translate() and fdt_get_base_address(), but
otherwise the rest is mostly annotation fixes:

Clean up libfdt.h includes

The libfdt.h file is the definition file for libfdt.  It is unnecessary
to include other fdt header files (the necessary ones are pulled in
by libfdt.h).
