[PATCH] nvmem: avoid false positive in of_nvmem_find() and simplify it

[Enrico Scholz]

of_nvmem_find() compared only the node names which can return the
wrong device in setups like

|  &i2c1 {
|      eeprom at 50 {
|      };
|  };
|  &i2c2 {
|      eeprom at 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.
