arm64: dts: qcom: msm8992-*: Fix up comments

Make sure all multiline C-style commends begin with just '/*' with
the comment text starting on a new line.

Also, trim off downstream regulator properties from comments to prevent
them from accidentally landing into mainline one day..

arm64: dts: qcom: msm8992-lg-bullhead: Place LG Bullhead generic code into a DTSI file

This patch puts the generic code common across all hardware revisions
into a DTSI file.

It also prefixes the DTS filename with the vendor name, to follow the
naming convention used by other DTS files.
