[PATCH v2 3/3] include: types: Add typedefs for endianness

[Rahul Pathak]

If any variable/memory-location follows certain
endianness then its important to annotate it properly
so that proper conversion can be done before read/write
from that variable/memory.

Also, use these new typedefs in libfdt_env.h for deriving
its own custom fdtX_t types
