Some STM32 devices embed a voltage reference buffer which can be used as
voltage reference for ADCs, DACs and also as voltage reference
for external components through the dedicated VREF+ pin.
This patchset adds vrefbuf regulator driver, device tree bindings and
vrefbuf device tree node for STM32H7 SoC.
