When the GMAC support was added to the bananapi-m2-ultra, regulators
weren't tied to the pinctrl. Fix that.

You should list all the regulators that are needed for all the pin
banks to operate properly, not just PA

I'm not sure what that is supposed to do?

Ok, I "think" I finally understand what you mean, so according to 
schematics in 
https://drive.google.com/file/d/0B4PAo2nW2KfndFpmZG1OOWJ5NEU/view, it 
should look like this

The R40 doesn't have them, so there's no suprise there :)

(if you ever want to find that info again in the future, the various
vcc-p* that you need to find are in the datasheet)
