The cells should be in DTSI, because you cannot have an enabled i2c bus
without nodes in normal cases. The not-normal case is incomplete
description, which does not happen here.

The pinctrls I guess as well in DTSI, because you do not customize the
pins in the DTS. IOW, if the pinctrl nodes are coming from shared
pinctrl.DTSI, then pinctrl-0/names stay in DTSI as well.


Best regards,
Krzysztof
