power: supply: qcom_battmgr: Register the power supplies after PDR is up

Browse source

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.
