Subject: [PATCH 0/6] arm64: dts: qcom: x1*: Fix vreg_l2j_1p2 voltage

Several of the Qualcomm X1* device trees upstream specify the wrong voltage
for the L2J regulator. In the ACPI DSDT table, PPP_RESOURCE_ID_LDO2_J is
configured with 1256000 uV instead of the 1200000 uV. Change all affected
device trees to use the same for consistency and correctness.

In the other device trees upstream, the voltage is already correct:
 - x1e78100-lenovo-thinkpad-t14s.dtsi
 - x1e80100-dell-xps13-9345.dts
 - x1e80100-microsoft-romulus.dtsi
