Since this is a part of a MFD I'd not expect it to have a compatible
string?

Since we switched to use devm_of_platform_populate() [1] to register
MFD subdevices, compatible is required, IIUC.

I'm not sure that's a good fit for these regulators, we don't gain any
extra information from the compatible here.
