Existing I2C code is for TrueTouch Gen3 devices

TrueTouch Gen4 device is using same protocol, will split driver into
two pieces to use common code with both drivers.

Read/Write functions parameter list modified, since shared code will
be used by two separate drivers and these drivers are not sharing same
structs, parameters updated to use common structures.
