iio: core: Introduce IIO_CHAN_INFO_OVERSAMPLING_RATIO
Some magnetometers can perform a number of repetitions in HW
for each measurement to increase accuracy. One example is
Bosch BMC150:
http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-04.pdf.
Introduce an interface to set the oversampling ratio
for these devices.
