docs: Make an I2C write/read access.
  
          First an I2C write access is issued. No stop condition will be
          generated. Instead the read access begins with a repeated start.
  
          This method is useful for accessing most addressable I2C devices like
          EEPROMs, port expander, etc.
  
          Basically, this is just a convenient function which internally uses
          `i2c_master_write` and `i2c_master_read`.
