Hi Mike

The binding should look to be as complete as possible, independent on what
we are actually using in the driver.

A quick glance at the datasheet shows me this device has 2 interrupt lines
dedicated to the accelerometer and 2 power supplies, vddio and vdd.

Interrupt lines for flexible parts like this are fiddly to do, so take
a look at how we do this in other drivers.  Hmm. the interrupt line to set
a tag is 'interesting'.  I'd ignore that for now...

Should reflect the compatible so include the accel part.
