This loop requires explicit calls to of_node_put() upon early exits (break, goto, return) to decrement the child refcounter and avoid memory leaks if the child is not required out of the loop.

A more robust solution is using the scoped variant of the macro, which automatically calls of_node_put() when the child goes out of scope.

Add compatible string for the SPMI block on MT8188 SoC, which is compatible with the one used on MT8195.

SAR2130P has SPMI v7 arbiter. Although it has only a single bus configuration, use the new bindings for v7 platforms.
