of: Fix phandle endian issues
The flat tree code wasn't fixing the endianness on phandle values when unflattening the tree, and the code in drivers/of wasn't always doing a be32_to_cpu before trying to dereference the phandle values. This patch fixes them. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
