This commit removes the I2C context from the LCD base class and moves it into each of the drivers. In addition, the createChar() virtual function was removed from the base class, as it directly used the now non-existant i2c context, and it would not work on anything other than hd44780 based controllers and displays anyway. Also, it is likely the capability itself, as well as the data required to implement it, is going to be different from device to device. createChar() has been added to the Lcm1602 driver which can support it. While doing this work, the LCD base class m_name is now set appropriately in the driver constructors.
