We need to perform a reset a start up to make sure that the chip is in a
consistent state. This reset also disables all the interrupts which
should only be enabled together with the iio buffer. Not doing this, was
sometimes causing unwanted interrupts to trigger.

Changes in v2:
- Instead of disabling the interrupts, now this patch performs
a software reset.
