[POWERPC] chrp: Constify & voidify get_property()
Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. chrp platform changes. Built for chrp32_defconfig Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
