Subject: [PATCH 3/8] arm64: dts: qcom: msm8939-sony-tulip: Fix l10-l12
 regulator voltages

msm8939-sony-xperia-kanuti-tulip.dts has several regulator voltages
that do not quite seem to match what is used in the vendor kernel.
In particular:

 - l10 is fixed at 2.8V [1, 2]
 - l11/l12 are 2.95V max [1]
