iio: imu: mpu6050: Fix alignment for DMA safety
____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.")
