ipa: Switch to FrameBuffer interface

Browse Source 
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.
