[PATCH] staging:iio: ak8975: add of_match table for device-tree probing

[Olof Johansson]

Just like isl29018; trivial addition. Using both asahi-kasei,ak8975 and
the non-prefixed version (I couldn't figure out if Asahi Kasei had a
stock symbol to use, I only found numerical indexes for their stock info).

Again, fine by me but a confirmation from someone more device tree
oriented would be great as well.

Unless there is a really good reason for it, drop the non-prefixed version.

Otherwise it looks okay by me.
