The mfg_async power domain in mt8173 is used to power up imgtec
gpu. This domain requires the da9211 regulator to be enabled before
the power domain can be enabled successfully.

Hm, I think the problem here is, that we don't find the regulator
"domain-supply" in the DTS. And that provokes that we error out on all power
domains. Not sure if we should fix that somehow, so that a missing regulator
will only affect one power domain (and it's childs).

Regards,
Matthias
