Is this change related?

A 'stdout-path' should make more sense here.

We had stopped doing this for a while, because DT maintainers do not
like this fake simple-bus container. Please put the fixed regulator
nodes directly under root with following naming schema.
reg_xxx: regulator-xxx {
...
};

We generally sort the device nodes under I2C bus in order of slave
address. That said, this pca9555 at 23 node should go before eeprom at 50.

Since commit 5fcdf6a7ed95 (pinctrl: imx: Allow parsing DT without
function nodes), this function container node is no longer needed.
