powerpc: Remove big endianness assumption in of_find_next_cache_node 

Currently big endianness of the device tree data is assumed in
of_find_next_cache_node for 'handle' when calling of_find_node_by_phandle.

In preparation to move this function to common code, this patch fixes
the endianness using 'be32_to_cpup'
