NOTE: this relies on the linked devicetree changes to land in Linux first and get synced here, otherwise the board will fail to boot! I'm leaving this as a RFC/RFT at this time for that reason until things get merged and synced over (if there's a faster way to get that done please let me know, otherwise I'll be patient. Maybe the cherry-picking described over at https://docs.u-boot.org/en/latest/develop/devicetree/control.html#resyncing-with-devicetree-rebasing would be appropriate to do *in* this series after that is merged in Linux?).
This enables the ESMs and the associated PMIC. Programming these bits is a requirement to make the watchdog actually reset the board. I've tested this series (with the linked change) on the k3-j784s4-evm, but not its sibling the k3-am69-sk. I'd appreciate at a minimum someone to test on that platform to ensure this doesn't break boot.
