msm: camera2: port VPE module to pproc framework
To better support Android Camera 2.0, the postprocessing component was
rewritten to be a generic module with sink ports and source ports to
communicate with other modules. An imaging pipeline can be formed by
linking some modules together. In the new framework, v4l2 subdevices
don't communicate with each other in the kernel. Instead, user space
code accesses different subdevice nodes, and coordinate among
themselves. This change ports the VPE driver into this new framework.
