Jonathan Cameron ad602e3347 iio: imu: mpu6050: Fix alignment for DMA safety
[ Upstream commit 54e03562bb960e78af050d2e550c28d77642ee44 ]

____cacheline_aligned is an insufficient guarantee for non-coherent DMA
on platforms with 128 byte cachelines above L1.  Switch to the updated
IIO_DMA_MINALIGN definition.

Fixes: 6b0cc5dce072 ("iio:imu:inv_mpu6050 Fix dma and ts alignment and data leak issues.")
