iio: adc: adi-axi-adc: add data size support for AD408X backend

Browse source

The AD408X AXI core can pack the sample data on the bus using different
word widths. Expose this through the data_size_set backend operation so
that frontends can program the packet format field (bits 3:2 of the
CNTRL_3 register) according to the ADC resolution: 20-bit, 16-bit and
14-bit map to packet format values 0, 1 and 2 respectively.
