fbdev: work around old compiler bug 

When building with a 4.1.x compiler on powerpc64 (at least) we get this
error:

drivers/video/logo/logo_linux_mono.c:81: error: logo_linux_mono causes a section type conflict

This was introduced by commit ae52bb2384
("fbdev: move logo externs to header file").  This is a partial revert of
that commit sufficient to not hit the compiler bug.

Also convert _clut arrays from __initconst to __initdata.

Sam said:

  Al analysed this some time ago.  When we say something is const then
  _sometimes_ gcc annotate the section as const(?) - sometimes not.  So if
  we have two variables/functions annotated __*const and gcc decides to
  annotate the section const only in one case we get a section type
  conflict.
