v5: 
sync with the series:
https://patchwork.kernel.org/project/linux-mediatek/list/?series=640196
   1. change title suggested by Krzysztof;
   2. No need drop 'reviewed-by Rob' suggested by Krzysztof
   3. add maintainer Lala who maintain efuse driver now;

v4: fix duplicated unit-address in example;
    drop reviewed-by Rob, due to changes;

v3: add reviewed-by Rob

v2:
   1. remove description of subnodes which is covered by nvmem.yaml suggested by Rob
   2. change the example which is commoner than mt8173's

-= Data consumers =

-For example:
-
-	thermal {
