Add basic functionality for LSM9DS1. This has become a trivial addition
by now.

Move some register definitions to the per-device array of struct
st_lsm6dsx_sensor_settings in order to simplify adding new sensor
devices to the driver.
Also, remove completely unused register definitions.

Martin Kepplinger
The LSM9DS1's accelerometer / gyroscope unit and it's magnetometer (separately
supported in iio/magnetometer/st_magn*) are located on a separate i2c addresses
on the bus.
For the datasheet, see https://www.st.com/resource/en/datasheet/lsm9ds1.pdf
Treat it just like the LSM6* devices and, despite it's name, hook it up
to the st_lsm6dsx driver, using it's basic functionality.
accelerometer and gyroscope are not independently clocked. It runs at the gyro
frequencies if both are enabled, see chapter 7.12 of the datasheet.
We could have handled this as a single IIO device but we have split
it up to be more consistent with the other more flexible devices.
