Introduce necessary plumbing to enable passing buffers
to VIMC IPA. The actions and events for IPA <> PH
handling is minimalistic for now, can be extended on top.

As discussed on IRC, absence of actual parameters and
statistics buffer is a concern. We could have created our
own, but those need to be backed by dmabuf/fds. We want
to leverage VIMC for tests for now, hence, we are passing
actual frame buffers to the IPA instead of the param/stats
ones.

  ipa: vimc: Add configure() function

  ipa: vimc: Rename IPA trace enums
  ipa: vimc: Map and unmap buffers
  ipa: vimc: Send and retrieve FrameBuffers from IPA
