The regulator_autoset() function mixes printf() output and PMIC adjustment code. It provides a boolean to control the output. It is better to avoid missing logic and output, and this permits a smaller SPL code size. So split the output into a separate function. Also rename the function to have a by_name() suffix, since we would like to be able to pass a device when we know it, and thus avoid the name search.
