staging: comedi: das08: Correct AI encoding for das08jr-16-ao
The element of `das08_boards[]` for the 'das08jr-16-ao' board has the `ai_encoding` member set to `das08_encode12`. It should be set to `das08_encode16` same as the 'das08jr/16' board. After all, this board has 16-bit AI resolution. The description of the A/D LSB register at offset 0 seems incorrect in the user manual "cio-das08jr-16-ao.pdf" as it implies that the AI resolution is only 12 bits. The diagrams of the A/D LSB and MSB registers show 15 data bits and a sign bit, which matches what the software expects for the `das08_encode16` AI encoding method.
