iio: adc: vf610_adc: Fix VALT selection value for REFSEL bits
[ Upstream commit d466d3c1217406b14b834335b5b4b33c0d45bd09 ]
In order to select the alternate voltage reference pair (VALTH/VALTL), the
right value for the REFSEL field in the ADCx_CFG register is "01", leading
to 0x800 as register mask. See section 8.2.6.4 in the reference manual[1].
