[PATCH -next] x86: olpc: fix section mismatch warning

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix section mismatch warning:

WARNING: vmlinux.o(.text+0x36e00): Section mismatch in reference from the function olpc_dt_compatible_match() to the function .init.text:olpc_dt_getproperty()
The function olpc_dt_compatible_match() references
the function __init olpc_dt_getproperty().
This is often because olpc_dt_compatible_match lacks a __init 
annotation or the annotation of olpc_dt_getproperty is wrong.

All calls to olpc_dt_compatible_match() are from __init functions,
so it can be marked __init also.
