xlat v2: Remove architectural headers

They only contained one function that is easily integrated in the private
library header and the existing architectural C files.

This also helps making the library more portable, as the Makefile of the
library now doesn't use the variable INCLUDES, which is specific to this
codebase and doesn't respect the namespace of the library.
