The camera subsystem for the MSM8939 is the same as MSM8916 except with
3 CSID instead of 2, and some higher clock rates.

As a quirk, this SoC needs writing values to 2 VFE VBIF registers
(see downstream msm8939-camera.dtsi vbif-{regs,settings} properties).
This fixes black stripes across sensor and garbage in CSID TPG outputs.

Add support for the MSM8939 camera subsystem.

I would repeat my ask given previously:

There shall be no more dragging of the .link_entities, it's gone
a bit more than 6 weeks ago.

For sake of simplicty you may include that particular change preserving
all its tags into your MSM8939 changeset, it will help a maintainer
to resolve merge conflicts.
