ipa: Switch to FrameBuffer interface
Switch the IPA interfaces and implementations to use the Framebuffer
interface.
- The IPA interface is switched to use the simpler FrameBuffer::Plane
container when carrying dmabuf descriptions (fd and length) over the
pipeline/IPA boundary.
- The RkISP1 IPA implementation takes advantage of the new simpler and
safer (better control over file descriptors) FrameBuffer interface.
