The whole point of naming the regulators is to help users read kernel
diagnostic output so the should normally be named after the supply in
the schematic.  If you're using the name of the supply on the PMIC you
can just omit it since that's the default anyway and it's not adding
extra information.  Use something like VCC_1V8.
