regulator: bd71815: bd71828: bd9576: Use dev_err_probe()

Browse Source 
The dev_err_probe() has (at least) following benefits over dev_err()
when printing an error print for a failed function call at a device
driver probe:
        - Omit error level print if error is 'EPRBE_DEFER'
        - Standardized print format for returned error
        - return the error value allowing shortening calls like:

        if (ret) {
                dev_err(...);
                return ret;
        }

        to

        if (ret)
                return dev_err_probe(...);

Convert the ROHM BD71828, ROHM BD71815 and ROHM BD9576 regulator drivers
to use the dev_err_probe() when returned error is not hard-coded constant.
