[PATCH 5/7] arm64: dts: qcom: msm8998-xperia: Configure display boost regulators

AngeloGioacchino Del Regno

Add configuration for the LAB and IBB regulators (in boost mode):
this platform has smartphones with three different display sizes,
hence different displays requiring different voltage.

The common configuration parameters have been put in the common
device-tree, while specific voltage specs and soft-start-us are
variant specific, so they have been put into the machine specific
dts file.
