iio: adc: ad9467: fix ad9434 vref mask

commit 92452b1760ff2d1d411414965d4d06f75e1bda9a upstream.

The mask setting is 5 bits wide for the ad9434
(ref. data sheet register 0x18 FLEX_VREF). Apparently the settings
from ad9265 were copied by mistake when support for the device was added
to the driver.
