Essential bindings like clock support are missing for 8 years. With 6MB of internal RAM only, N1S is not a prime candidate for running Linux, unlike the DDR-RAM capable N1D. I could not find any further activity in upstreaming N1S support, neither for Linux or any other OS. So, remove these half-baked dangling bindings which are incomplete and look unprofessional. We can happily add them back if somebody offers complete support for it. Until then, let's enjoy the easier handling of a single 'const'.
