iio: adc: ad4080: configure backend data size
The AXI backend needs to know the ADC word width in order to pack the
sample data correctly on the bus. During channel setup, program the
backend packet format via iio_backend_data_size_set() using the channel
resolution, so the data is transferred according to the device's
realbits.
The backend packet format field defaults to 20-bit packing, so the
20-bit parts (AD4080/AD4081/AD4082, AD4880) were unaffected. The 16-bit
(AD4083/AD4084/AD4085, AD4884) and 14-bit (AD4086/AD4087/AD4088) parts,
however, were left packing data at the wrong width, producing corrupt
buffered captures.
