[PATCH RFC/RFT v2 0/4] k3-j784s4-r5-evm: Enable ESMs and related PMIC

[Andrew Halaney]

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.
