From: Maarten Lankhorst <maarten.lankho...@linux.intel.com>
We need to look at hw.fb for the framebuffer, and add the translation
for the slave_plane_state. With these changes we set the correct
rectangle on the bigjoiner slave, and don't set incorrect
src/dst/visibility on the slave plane.
v2:
* Manual rebase (Manasi)
v3:
* hw.rotation instead of uapi.rotation (Ville)
