This is in the MFD, this is not used in actual systems.

Not sure what you mean by "actual systems", it looks like these
use it?:

arch/arm/boot/dts/mt8135-evbp1.dts
arch/arm64/boot/dts/mediatek/mt8173-evb.dts

To repeat: the regulator driver does not register a compatible string
for the device for device model probing.

I understand this, I thought we are talking about compatible strings in
the regulator sub-node, not how the core instantiates the sub-driver.

No, this exactly about how the device model devices are instantiated.
