Jonathan Cameron ab03f15c1d iio: dac: ad5624r: Fix incorrect handling of an optional regulator. 
[ Upstream commit 97683c851f9cdbd3ea55697cbe2dcb6af4287bbd ]

The naming of the regulator is problematic.  VCC is usually a supply
voltage whereas these devices have a separate VREF pin.

Secondly, the regulator core might have provided a stub regulator if
a real regulator wasn't provided. That would in turn have failed to
provide a voltage when queried. So reality was that there was no way
to use the internal reference.

In order to avoid breaking any dts out in the wild, make sure to fallback
to the original vcc naming if vref is not available.
