Brian Norris 7e198197ec 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.
