Subject: [PATCH v2 08/11] powerpc/prom_init: mark prom_getprop() and prom_getproplen() as __init

This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place. We need to eliminate potential issues beforehand.

If it is enabled for powerpc, the following modpost warnings are
reported:

WARNING: vmlinux.o(.text.unlikely+0x20): Section mismatch in reference from the function .prom_getprop() to the function .init.text:.call_prom()
The function .prom_getprop() references
the function __init .call_prom().
This is often because .prom_getprop lacks a __init
annotation or the annotation of .call_prom is wrong.

WARNING: vmlinux.o(.text.unlikely+0x3c): Section mismatch in reference from the function .prom_getproplen() to the function .init.text:.call_prom()
The function .prom_getproplen() references
the function __init .call_prom().
This is often because .prom_getproplen lacks a __init
annotation or the annotation of .call_prom is wrong.
