[PATCH 4/5] arm64: dts: qcom: msm8916-huawei-g7: Add display regulator

[Stephan Gerhold <stephan@gerhold.net>]

The display on the Huawei Ascend G7 is supplied by a TI TPS65132
regulator. The panel needs a driver in mainline first, but the
TPS65132 is already supported in mainline by the tps65132 driver.
