Power domain fits much better than a voltage regulator in regards to
a proper hardware description and from a software perspective as well.
Hence replace the core regulator with the power domain. Note that this
doesn't affect any existing DTBs because we haven't started to use the
regulator yet, and thus, it's okay to change it.

'power-domains' already has a type. We need to know how many (maxItems).

Alright, I see now what makes the difference. Thank you and Krzysztof
for the suggestion.
