drivers: i2c: add a simple framework to handle i2c devices
Add simple i2c support which provides support for I2C controllers and
devices using the generic DT mechanisms that already exists. I2C
controllers needs to implement i2c_ctrl_ops to provide i2c operations
such as read, write and smbus commands depending on their capabilities.
I2C devices driver can then be defined using DEFINE_I2C_DEV_DRIVER().
This macros will use a default i2c probe function (__i2c_probe()) which
will then call the I2C device probe function by passing a i2c_dev struct
that can be used to communicate with the I2C device defined in the
device-tree.
