powerpc/64s: Always disable branch profiling for prom_init.o 

[ Upstream commit 6266a4dadb ]

Otherwise the build fails because prom_init is calling symbols it's
not allowed to, eg:

  Error: External symbol 'ftrace_likely_update' referenced from prom_init.c
  make[3]: *** [arch/powerpc/kernel/Makefile:197: arch/powerpc/kernel/prom_init_check] Error 1
