Accelerometer parameter address missing in Docs

[Christoph Labacher]

The docs for the parameters of accelerometers do not mention the address parameter. However, since the initializers of ADXL345, MMA8452 and MMA7660 call Drivers.addressResolver(this, options);, the options.address can be used to set the address.

Unfortunately I couldn’t figure out where to update this information, if you point me to it I’ll submit a PR :)
