[PATCH 2/4] arm64: dts: qcom: sm6115p-j606f: Hook up display

[Konrad Dybcio <konrad.dybcio@linaro.org>]

Enable the required nodes, add the required pins and tweak a
regulator to enable non-simplefb display on the Tab P11.

Do note that there exists a second SKU with a different panel+touch
combo, but due to insufficient information, that will need to be
handled separately.
