power: regulator: max77686 correct variable type
The return type of pmic_read and pmic_write is signed int, so
correct variable 'ret' from type unsigned int to int.

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.

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.

sandbox: add: sandbox PMIC device drivers: I2C emul, pmic, regulator
This commit adds emulation of sandbox PMIC device, which includes:
- PMIC I2C emulation driver
- PMIC I/O driver (UCLASS_PMIC)
- PMIC regulator driver (UCLASS_REGULATOR)
The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes,
which allows using 'i2c md' command with the default count (16).
The sandbox PMIC provides regulators:
- 2x BUCK
- 2x LDO
Each, with adjustable output:
- Enable state
- Voltage
- Current limit (LDO1/BUCK1 only)
- Operation mode (different for BUCK and LDO)
Each attribute has it's own register, beside the enable state, which depends
on operation mode.
The header file: sandbox_pmic.h includes PMIC's default register values,
which are set on i2c pmic emul driver's probe() method.

dm: regulator: add fixed voltage regulator driver
This driver implements regulator operations for fixed Voltage/Current
value regulators. beside the standard regulator constraints, which are
put into the uclass platform data, a typical fixed regulator node provides
few additional properties like:
- gpio
- gpio-open-drain
- enable-active-high
- startup-delay-us
The only 'gpio' is used by this driver and is kept in structure of type
'fixed_regulator_platdata', as a device platform data (dev->platdata).
The driver implements:
- get_value
- get_current
- get_enable
- set_enable
The regulator calls and commands can be used for fixed-regulator devices,
and the proper error will be returned for prohibited.
