At least the sun6i DMA controller driver makes use of the reset controller
API stubs when being built for coverage and otherwise fails to build.

I'd prefer to keep devm_reset_control_get without a stub.
Drivers that can be built without CONFIG_RESET_CONTROLLER enabled should
use devm_reset_control_get_optional, and this way the build tests
already report this issue.
