of_nvmem_find() compared only the node names which can return the
wrong device in setups like
| &i2c1 {
| eeprom@50 {
| };
| };
| &i2c2 {
| eeprom@50 {
| };
| };
Instead of checking the complete path ('full_name' attribute), the
patch compares the device_node pointers directly.
This is done in other places (e.g. of_find_i2c_adapter_by_node()) and
in the linux kernel too.
