without that stub, drivers will fail to build
when CONFIG_RESET_CONTROLLER=n.

reset_control_get should only be used in cases where the reset
controller is mandatory for the driver to work, and hence, this driver
should select or depend on CONFIG_RESET_CONTROLLER
If the reset controller is optional, reset_control_get_optional should
be preferred, that is stubed out.
