Plane color space conversion is different on GLK and later platforms causing the colors to display incorrectly. Ville's plane color space property patch series in review will fix this issue. - Restricted the NV12 case in intel_framebuffer_init to SKL and BXT only. v6: Rebased (me) v7: Addressed review comments by Ville Restricting the NV12 to BXT for now. v8: Rebased (me) Restricting the NV12 changes to BXT and KBL for now. v9: Rebased (me) v10: NV12 supported by all GEN >= 9. Making this change in intel_framebuffer_init. This is part of addressing Maarten's review comments.
