Generalize st_lsm6dsx_shub_read_oneshot in order to not use a fixed
read length and take into account iio channel realbits for single
read operations

Introduce hw FIFO support to lsm6dsx i2c controller.
st_lsm6dsx sensor-hub relies on SLV0 for slave configuration since SLV0
is the only channel that can be used to write into i2c slave devices.
SLV{1,2,3} channels are used to read external data and push them into
the hw FIFO

i2c controller embedded in lsm6dx series can connect up to four
slave devices using accelerometer sensor as trigger for i2c
read/write operations.
Introduce sensor hub support for lsm6dso sensor. Add register map
for lis2mdl magnetometer sensor.
In order to perform single read/write operations st_lsm6dsx driver
relies on SLV0 channel (hw FIFO is not supported yet)
