iio: adc: ad4080: fix chip identification
commit b66cddc8be7278fd14650ff9182f3794397f8b31 upstream.
Fix AD4080 chip identification by using the correct 16-bit product ID
(0x0050) instead of GENMASK(2, 0). Update the chip reading logic to
use regmap_bulk_read to read both PRODUCT_ID_L and PRODUCT_ID_H
registers and combine them into a 16-bit value.
The original implementation was incorrectly reading only 3 bits,
which would not correctly identify the AD4080 chip.
