Add an overlay for MSM8996v3.0, which is a pre-final revision
of the said SoC. It has some stark differences with regards to
GPU, or more specifically its power delivery path. Oh, and of
course a different msm-id.

Changes since v1:
- Apply the OPP table by default when this tree is included
- Switch to BSD3
