The I2C bus register memory regions and I2C bus pool buffer memory regions are discontinuous and they do not back compatible AST2600. Add a new ast2700 i2c class init function to match the address of I2C bus register and pool buffer from the datasheet. An I2C controller registers owns 8KB address space.
