[PATCH] powerpc: fix ics_rtas_init and start_secondary section mismatch

[Daniel Borkmann <dborkman@redhat.com>]

It seems, we're fine with just annotating the two functions.
Thus, this fixes the following build warnings on ppc64:

WARNING: arch/powerpc/sysdev/xics/built-in.o(.text+0x1664):
The function .ics_rtas_init() references
the function __init .xics_register_ics().
This is often because .ics_rtas_init lacks a __init
annotation or the annotation of .xics_register_ics is wrong.

WARNING: arch/powerpc/sysdev/built-in.o(.text+0x6044):
The function .ics_rtas_init() references
the function __init .xics_register_ics().
This is often because .ics_rtas_init lacks a __init
annotation or the annotation of .xics_register_ics is wrong.

WARNING: arch/powerpc/kernel/built-in.o(.text+0x2db30):
The function .start_secondary() references
the function __cpuinit .vdso_getcpu_init().
This is often because .start_secondary lacks a __cpuinit
annotation or the annotation of .vdso_getcpu_init is wrong.
