iio: dac: ad5686: add AD5695R to ad5686_chip_info_tbl

The chip info for this variant (I2C, four channels, 14 bit, internal
reference) seems to have been left out due to oversight, so
ad5686_chip_info_tbl[ID_AD5695R] is all zeroes. Initialisation of an
AD5695R still succeeds, but the resulting IIO device has no channels and no
/dev/iio:device* node.

Add the missing chip info to the table.
