[POWERPC] Make get_property() return a const void *
Previous changes have treated the return values of get_property as
const, so now we can make the actual change to get_property(). There
shouldn't be a need to cast the return values anymore.
We will now get compiler warnings when property values are assigned to
a non-const variable.
If properties need to be updated, there's still the of_find_property
function.
Built for cell_defconfig, chrp32_defconfig, g5_defconfig,
iseries_defconfig, maple_defconfig, pmac32_defconfig, ppc64_defconfig
and pseries_defconfig.
