staging:iio:gyro:adis16260 move to chan_spec based setup.

Browse Source 
For clean drivers its easier to convert to chan_spec based
registration than to work around the scan_el attributes
going away.

Some minor cleanups done whilst here.

Untested.
V3: rebase fixup and make attribute_group static.

V2: IIO_CHAN macro updates.
