[ Upstream commit b43f7ddc2b7a5a90447d96cb4d3c6d142dd4a810 ]
Currently, a not-yet-entirely-initialized battmgr (e.g. with pd-mapper not having yet started or ADSP not being up etc.) results in a couple of zombie power supply devices hanging around.
This is particularly noticeable when trying to suspend the device (even s2idle): the PSY-internal thermal zone is inaccessible and returns -ENODEV, which causes log spam.
Register the power supplies only after we received some notification indicating battmgr is ready to take off.
