odroid: enable driver model pmic/regulator API and MAX77686 drivers

This change enables the configs required to init and setup max77686
regulator driver, using the new driver model pmic and regulator API.
And also changes the old pmic framework calls to the new ones.

This commits enables:
- CONFIG_ERRNO_STR
- CONFIG_DM_PMIC
- CONFIG_DM_PMIC_CMD
- CONFIG_DM_PMIC_MAX77686
- CONFIG_DM_REGULATOR
- CONFIG_DM_REGULATOR_CMD
- CONFIG_DM_REGULATOR_MAX77686

And removes the unused:
- CONFIG_DM_I2C_COMPAT
- CONFIG_POWER
- CONFIG_POWER_I2C
- CONFIG_POWER_MAX77686
