[PATCH 1/2] power:lp8727_charger: use the private data instead of updating I2C device platform data

Currently, lp8727 charger driver parses the DT and copies values into the 'cl->dev.platform_data' if 'of_node' exists. This may have architectural issue. Platform data is configurable through the DT or I2C board info inside the platform area. However, lp8727 driver changes this configuration when
