Currently we have neither dependency nor reverse-selection of CONFIG_RESET_CONTROLLER. It wouldn't be a problem for builds, but you'll get a runtime error from devm_reset_control_array_get_exclusive() always when CONFIG_RESET_CONTROLLER=n.
I guess it must be a corner case, but just to be sure.
The CONFIG_RESET_CONTROLLER=y at least for ARM32 Tegra builds.

Not sure about ARM64.
OK, then it must be fine. I applied now. Thanks.
