drivers/sensor: lsm6dso: Add support for lsm6dso32

This sensor is virtually identical to the lsm6dso.  The only difference
is the accelerometer ranges are double those of the lsm6dso.

Use the same driver.  The difference is detected by using "st,lsm6dso32"
as the first compatible entry, followed by "st,lsm6dso".

An bit flag in the existing accel_range config field is used to check if
the chip is the doubled range or not.
