[ Upstream commit 887b528c958f40b064d53edd0bfa9fea3a69eccd ]
The current l3 min voltage level is not supported by the regulator (the voltage is not a multiple of the regulator step size), so a driver requesting this exact voltage would fail, see discussion in: https://patchwork.kernel.org/comment/22461199/
It was agreed upon to set a min voltage level that is a multiple of the regulator step size.
There was actually a patch sent that did this: https://patchwork.kernel.org/patch/10819313/
However, the commit 331ab98f8c4a ("arm64: dts: qcom: qcs404: Fix voltages l3") that was applied is not identical to that patch.
