iio: st_accel: support 8bit channel data
Some sensors like the LIS331DL only support 8bit data by a single
register per axis. These utilize the MSB byte. Make it possible
to register these apropriately.
A oneliner change is needed in the ST sensors core to handle 8bit
reads as this is the first supported 8bit sensor.
