For compile test, right, "depends on RESET_CONTROLLER" is
redundant in the first place.

For run-time on real SoCs,the driver failed at the following point
without the reset-controller sub-system.


sspi->rstc = devm_reset_control_get(&pdev->dev, NULL);
if (IS_ERR(sspi->rstc)) {
dev_err(&pdev->dev, "Couldn't get reset controller\n");
ret = PTR_ERR(sspi->rstc);
goto err_free_master;
}
