ARM: dts: stm32: Remove buck3 regulator-always-on on AV96

Browse Source 
In case the regulator-always-on is present in regulator DT node,
the regulator is always reconfigured to the voltage set in DT on
probe, even if regulator_set_value() has been called before. Drop
the property from AV96 U-Boot DT and enable the regulator manually
in code, as the board already reconfigures the Buck3 regulator in
code per PMIC NVM content instead.
