Hello,

The first patch adds support for configuring the Sampling frequency
(inter-measurement period) of the sensor. The values must be provided
in miliseconds. The default value for the inter-measurement period for
ALS is 10ms and for Range is 50ms.

The second patch adds support for interrupt based single shot reading.
We registered an irq_handler that fires everytime the data is ready.
And then we read the appropriate value in the `vl6180_measure` routine.

The third patch adds support for continuous mode in the sensor by using
buffers. We enable the sensor's continuous mode in the buffer_postenable
function depending on the `active_scan_mask`.
The continuous mode can be disabled by disabling the buffer.
Added a trigger to the device for the continuous mode. Also validating that
the device uses the internal trigger provided by us.

Thanks,
Abhash Jha
