Driver doesn't compile for 5.9.0+ - iio_priv_to_dev() helper migration

[joax]

The helper is decommissioned from iio so this driver (apple-ib-als.c in particular) needs a different strategy to access the private components of the device. I am trying to re code to this new world, I will post a PR soon unless you have one already in the making.

Had the same error. I used this to patch mine.
