powerpc/mpc512x: remove unnecessary #if
Several functions are only ever referenced locally, so make them static. Of those functions, many of them are protected by an #if. However, the code which can compile fine in either case. Now that (1) the unneeded code is marked 'static' and (2) the code is only used under a C 'if (IS_ENABLED(CONFIG_FB_FSL_DIU))', the compiler can automatically remove the unneeded code, and we don't need the #if or the empty stub functions.
