This sensor can perform samples averaging in hardware, but currently the
driver leaves this setting alone (default is no averaging).
This patch binds this HW setting to the "oversampling_ratio" IIO attribute
and allows the user to set the averaging as desired (the HW supports
averaging of 2, 5, 8 or 16 samples; in-between values are rounded up).
