Updated doc for new deviceOS 1.5 features

I checked the reference docs for Boron and I couldn’t find any updates for the new interfaces for PMIC and sleep configuration.
There are some basic examples in the related Github issues, and some comments in the device code itself, but that’s about all I could find.
Any ETA for more documentations about these new features?

1.5.0 is still in “release candidate” status. I think the OS updates post said it’s scheduled to go “live” on Feb 21, if no major problems are found? So I would expect the documentation updates to appear at that time.
