  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 BD718x7 and ROHM BD9576 core drivers to
use the dev_err_probe() when returned error is not hard-coded constant.
