This change does that; the unwind order is preserved. What is important, is that the devm_iio_kfifo_buffer_setup() be called after the indio_dev->modes is assigned, to make sure that INDIO_BUFFER_SOFTWARE flag is set and not overridden by the assignment to indio_dev->modes. Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of 'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().

This mechanism estimates device internal clock by comparing FIFO interrupts delta time and device elapsed time computed by parsing FIFO data. Take interrupt timestamp in hard irq handler and add IIO device specific timestamp structures in device private allocation.

Add accel and gyro kfifo buffer and FIFO data parsing. Use device interrupt for reading data FIFO and launching accel and gyro parsing. Support hwfifo watermark by multiplexing gyro and accel settings. Support hwfifo flush.
