David Gibson 2cf86939af libfdt: Abolish fdt_offset_ptr_typed()
The fdt_offset_ptr_typed() macro seemed like a good idea at the time.
However, it's not actually used all that often, it can silently throw
away const qualifications and it uses a gcc extension (typeof) which
I'd prefer to avoid for portability.

Therefore, this patch gets rid of it (and the fdt_offset_ptr_typed_w()
variant which was never used at all).  It also makes a few variables
const in testcases, which always should have been const, but weren't
caught before because of the aforementioned silent discards.
