[PATCH 3/5] ARM: dts: stm32: remove fixed regulator unit address on stm32429i-eval

[Fabrice Gasnier <fabrice.gasnier@xxxxxx>]

vref fixed regulator shouldn't have unit address and reg properties.
Rename the label and phandle to "vref" according to the schematics.
Also remove it from simple-bus.

Fixes: 7465d81191a1 ("ARM: dts: stm32: enable ADC on stm32f429i-eval
board")
