staging:iio:sca3000: Register same channels for device and buffer 

In preparation for moving the buffer registration to the core make sure to
register the same channel array for the device and the buffer. Currently
the temperature channel is not registered for the buffer, setting its scan
index to -1 will make sure that it is skipped for the buffer.
