Some regulators will not implement any operations (e.g. fixed regulators).
This is not an error, so allow the autoset process to continue when one
of these regulators is found.

The currect PMIC debugging is a little confusing. Adjust it so that it is
clear whether the operation succeeded or failed. Also, avoid creating a new
error return value when a perfectly good one is already available.

Some devices are supplied by configurable regulator's output.
But there was no function for getting it. This commit adds
function, that allows for getting the supply device by it's phandle.
The returned regulator device can be used with regulator uclass's API.

If there is no property named 'regulator-name' for regulators,
choose node name instead, but not directly return failure value.

Not all regulators can be set up automatically. Adjust the code so that
regulators_enable_boot_on() will return success when some are skipped.
Only genuine errors are reported.

To reduce unnecessary code size in an uncommon code path, use debug()
where possible(). The driver returns an error which indicates failure.

The device tree provides information about which regulators should be
on at boot, or always on. Use this to set them up automatically.

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.

Decide when the regulator is set up whether we want to auto-set the voltage
or current. This avoids the complex logic spilling into the processing code.

This commit introduces the implementation of dm regulator API.
Device tree support allows for auto binding. And by the basic
uclass operations, it allows to driving the devices in a common
way. For detailed informations, please look into the header file.
Core files:
- drivers/power/regulator-uclass.c - provides regulator common functions api
- include/power/regulator.h - define all structures required by the regulator
Changes:
- new uclass-id: UCLASS_REGULATOR
- new config: CONFIG_DM_REGULATOR
