stable inclusion from stable-v6.6.2 commit 46a5ced7f68b7924cb76417564c2846f8b501ec4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G

--------------------------------
[ Upstream commit 31bee70793b67f4b428825434542afc72ddb2b3b ]
Commit b4fe47d12f1f ("arm64: dts: qcom: qrb2210-rb1: Add regulators") introduced regulator settings that were never put in place, as all of the properties ended 'microvolts' instead of 'microvolt' (which dt schema did not check for back then).
Fix the microvolts-microvolt typo and adjust voltage ranges where it's necessary to fit within the volt = base + n*step formula.
