For example if regulator device registration is optional in the code. We
don't have such cases in the kernel today, but I decided that it will be
cleaner to add stubs for the whole API.

The point of these stubs is to fix the new compile-testing problem of
Tegra regulator coupler drivers. The drivers indeed don't depend on the
regulator-driver API since the regulator-consumer API provides all the
necessary stubs, but now drivers use the regulator-driver API too. The
dependency should reduce the compile-testing scope, IIUC.

If you think that it will be better to add the dependency to the coupler
drivers, then let's do it.
