This commit adds a generic i2c regulator driver, and enables the NXP PCA9420 PMIC IC using this driver. The regulator driver also exposes an additional API in include/drivers/regulator/consumer.h, which allows drivers to implement support for adjusting voltage levels and current limits, if their device supports it.

I2C based regulator init priority.
|
|
Must be greater than KERNEL_INIT_PRIORITY_DEVICE so I2C is initialized,
|
|
and less than SDMMC_INIT_PRIORITY, since the SDMMC driver uses an I2C
