[PATCH] powerpc/prom_init: add __init markers to all functions

[Masahiro Yamada]

It is fragile to rely on the compiler's optimization to avoid the
section mismatch. Some functions may not be necessarily inlined
when the compiler's inlining heuristic changes.

Add __init markers consistently.

As for prom_getprop() and prom_getproplen(), they are marked as
'inline', so inlining is guaranteed because PowerPC never enables
CONFIG_OPTIMIZE_INLINING. However, it would be better to leave the
inlining decision to the compiler. I replaced 'inline' with __init.
