[POWERPC] powermac: 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.
powermac platform & macintosh driver changes.
Built for pmac32_defconfig, g5_defconfig
