Subject[RFC v2] iio: st_sensors: Add lsm9ds0-accel and lsm9ds0-magn support
Date
Because these devices shared the same I2C address/SPI chipselect they can't be
used at the same time.

The proper way to do this is as a single iio device but that requires
larger changes to st_sensors infrastructure.

I'm only posting this as a reference point. When a combo device is supported it
won't make sense to also support the -accel and -magn parts separately. So it
would be better if this support never makes it upstream.

Changes since v1:
* Fix ST_MAGN_4_DRDY_INT_MASK value
* Mention device ids are also mentioned in Kconfig
