powerpc/book3e: get rid of #include <generated/compile.h>
You cannot include <generated/compile.h> here because it is generated
in init/Makefile but there is no guarantee that it happens before
arch/powerpc/mm/nohash/kaslr_booke.c is compiled for parallel builds.
The places where you can reliably include <generated/compile.h> are:
- init/ (because init/Makefile can specify the dependency)
- arch/*/boot/ (because it is compiled after vmlinux)
Commit f231e4333312 ("hexagon: get rid of #include <generated/compile.h>")
fixed the last breakage at that time, but powerpc re-added this.
<generated/compile.h> was unneeded because 'build_str' is almost the
same as 'linux_banner' defined in init/version.c
Let's copy the solution from MIPS.
(get_random_boot() in arch/mips/kernel/relocate.c)
Fixes: 6a38ea1d7b94 ("powerpc/fsl_booke/32: randomize the kernel image offset")
