[PATCH v5 1/3] iio: imu: inv_icm42600: move structure DMA buffers at the end

[Jean-Baptiste Maneyrol via B4 Relay]

From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@xxxxxxx>

Move DMA buffers at the end of the structure to avoid overflow
bugs with unexpected effect.

struct inv_icm42600_fifo has a DMA buffer at the end.

Signed-off-by: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@xxxxxxx>
