Joseph Chen 6999767bb2 dm: regulator: add "regulator-loader-ignore" property support
The property indicates this regulator should skip init setting
sequence, usually for saving boot time.

Joseph Chen 0ae9790ca7 dm: regulator: drop regulator-state-mem initial from autoset
init regulator-state-mem wastes time a lot and is only needed when
system suspend is called, so provide regulators_enable_state_mem()
the driver that implements system suspend.

Keerthy 2f5d532f3b power: regulator: Introduce regulator_set_value_force function
In case we want to force a particular value on a regulator
irrespective of the min/max constraints for testing purposes
one can call regulator_set_value_force function.

Keerthy 34514b8b9c power: regulator: Add ctrl_reg and volt_reg fields for pmic
The ctrl reg contains bit fields to enable and disable regulators,
and volt_reg has the bit fields to configure the voltage values.
The registers are frequently accessed hence make them part
of dm_regulator_uclass_platdata structure.

Przemyslaw Marczak 7c816e24a4 dm: regulator: add function device_get_supply_regulator()
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.

Simon Glass 3b55d30f6f dm: pmic: Split output from function
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.

Przemyslaw Marczak 1757df4693 dm: regulator: add max77686 regulator driver
This commit adds support to MAX77686 regulator driver,
based on a driver model regulator's API. It implements
almost all regulator operations, beside those for setting
and geting the Current value.
For proper bind and operation it requires the MAX77686 PMIC driver.

Przemyslaw Marczak af41e8db26 dm: regulator: add implementation of driver model regulator uclass
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
