Subject: [PATCH v3 0/7] Fix dtbs_check warnings in CSI overlays

There are a bunch of new warnings generated using CONFIG_OF_ALL_DTBS.
This configuration applies DTB and overlay together to generate test DTBs,
which are then validated using dtbs_check.

This patch series fixes all warnings related to sensor overlays on
jacinto platforms and a few minor warnings on sitara as well.

To fix some of the warnings, missing power regulator nodes are added on
the J721E-SK and the regulator hierarchy on the AM68-SK is corrected.
