staging:iio:imu:adis16400 add support for adis16300

Browse Source 
Next patch will remove original driver.
Note this leaves holes in the scan indexing.

Untested - except via adis16350...

V3: rebase fixup.
V2: move to single IIO_CHAN macro.

adis16355, adis16360, adis16362, adis16364, adis16365, adis16400 and
adis16405 triaxial inertial sensors (adis16400 series also have
magnetometers).
