soc: mediatek: mtk-svs: restore default voltages when svs_init02() fail

Browse source

[ Upstream commit a0674cd237 ]

If svs init02 fail, it means we cannot rely on svs bank voltages anymore.
We need to disable svs function and restore DVFS opp voltages back to the
default voltages for making sure we have enough DVFS voltages.
