Good point. I remember some patch from Javier trying to address this but
I cannot find it anymore.
Anyway, I don't think power-domains should be treated here differently
then rest of devices (which have generic names: clock-controller,
pinctrl, i2s, i2c etc).

I am trying to bring some shape to new code but of course you are right
- old code should be adjusted as well (maybe as part of some bigger
cleanup). Exynos5420 uses short/generic names.
