Actually, ufshcd-qcom complains if they are missing:

[ 3.287836] ufshcd-qcom 1d84000.ufshc: ufshcd_populate_vreg: unable
to find vcc-max-microamp
[ 3.331904] ufshcd-qcom 1d84000.ufshc: ufshcd_populate_vreg: unable
to find vccq-max-microamp
[ 3.346766] ufshcd-qcom 1d84000.ufshc: ufshcd_populate_vreg: unable
to find vccq2-max-microamp
