iio: imu: adis16475: add spi_device_id table

[ Upstream commit ee4d79055aeea27f1b8c42233cc0c90d0a8b5355 ]

This prevents the warning message "SPI driver has no spi_device_id for..."
when registering the driver. More importantly, it makes sure that
module autoloading works as spi relies on spi: modaliases and not of.

While at it, move the of_device_id table to it's natural place.
