i2c blocking with multiple devices

[nigeltiany]

I tried using two i2c devices but i get event errors with this setup.

    devices: {
        pca: { driver: 'pca9685' },
        gyro: { driver: 'mpu6050' }
    },

The error is

events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: ENXIO, No such device or address
    at Error (native)

I have to comment out one device for it to work. I wasn't able to pin point the exact point in the code(cylon core or i2c driver) that does the blocking but if anyone can please point it out and i'll work on it. @deadprogram. There might be a callback that gets executed and closes out i2c after the first device.
