iio: max1363: Use devm_regulator_get_optional for optional regulator
In kernel version 3.13, devm_regulator_get() may return no error
if a regulator is undeclared. regulator_get_voltage() will return
-EINVAL if this happens. This causes the driver to fail loading if
the vref regulator is not declared.
Since vref is optional, call devm_regulator_get_optional instead.
