Subject: [PATCH 2/2] iio: pressure: mpl115: do not rely on structure field ordering

Fixes a regression triggered by a change in the layout of
struct iio_chan_spec, but the real bug is in the driver which assumed
a specific structure layout in the first place.

Fixes: 3017d90e8931 ("iio: Add Freescale MPL115A2 pressure / temperature sensor driver")
Fixes: 51239600074b ("iio:core: add a callback to allow drivers to provide _available attributes")
