Several functions are only ever referenced locally, so make them static.
Of those functions, many of them are protected by an #if. However, the

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.

v2: left out a diff I was holding locally (to remove an #if/#endif
    completely). Sorry for the noise.

Based off of Gerhard Sittig's patch:

Compile-tested with CONFIG_FB_FSL_DIU=n
