drm/{i915,xe}: move framebuffer bo to parent interfaceAdd .framebuffer_init, .framebuffer_fini and .framebuffer_lookup to thebo parent interface. While they're about framebuffers, they'respecifically about framebuffer objects, so the bo interface is a goodenough fit, and there's no need to add another interface struct.Reviewed-by: Suraj Kandpal Link: https://patch.msgid.link/848d32a44bf844cba3d66e44ba9f20bea4a8352d.1773238670.git.jani.nikula@intel.comSigned-off-by: Jani Nikula List of files: /linux/drivers/gpu/drm/xe/display/xe_display_bo.c

drm/{i915, xe}/bo: move display bo calls to parent interfaceContinue i915 and xe separation from display by moving the bo calls tothe display parent interface. Instead of adding all these functions tointel_parent.[ch], reuse the now vacated intel_bo.[ch], and avoid massrenames to calls of these functions. This is similar tointel_display_rpm.[ch].Make many of the hooks optional to avoid having to implement dummyfunctions in xe. Indeed now we can remove many of the existing dummyfunctions.Reviewed-by: Suraj Kandpal Link: https://patch.msgid.link/7899eef2ccf0cd603df69099df065226a0df917b.1773238670.git.jani.nikula@intel.comSigned-off-by: Jani Nikula List of files: /linux/drivers/gpu/drm/xe/display/xe_display_bo.c
