[PATCH v2 2/3] ARM: dts: stm32: fix vdda supply for onboard hub on stm32mp157c-ev1

stm32mp157c-ev1 uses Microchip USB2514 HUB. Since vdda supply has been
added, the regulator framework wrongly associates the 'vdda' supply
dedicated to ADC, so the wrong regulator is referenced.
Only the 3v3 regulator is used to supply both the digital and the analog
part of the HUB.
