iio: imu: adis16400: move adis16400.h into adis16400.c
Final part of the re-organization. Move the `adis16400.h` into `adis16400.c` since it no longer needs to be shared among other files. Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
