iio: adis16260: Add ADIS16266 support
The ADIS16266 is mostly register compatible to the ADIS16260. The difference is a different gyroscope scale factor as well not having the relative angular displacement channel. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
