PATCH 1/2 iio:accel:bmc150-accel: Move bmc150_accel_chip_init()

Move bmc150_accel_chip_init() so that we can use
bmc150_accel_chip_info_tbl[] in it.

Signed-off-by Bastien Nocera <[email protected]>

Whilst it would be nice to have this in stable etc it's going to need some backporting. For now I've applied it by hand to the togreg branch of iio.git (late in cycle so I'm wary of pushing this out in a fixes patchset).

I have marked it as for stable, but it almost certainly won't apply as is. (or at least the chances of both applying is rather small!)
