drm/i915: extract intel_fbc.h from intel_drv.h It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes. v2: Remove stray newline (Chris) Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/db44ba199c86f24bfa9e490531eddf51cccd89da.1554461791.git.jani.nikula@intel.com

drm/i915/fbc: Move the plane state check into the fbc functions Instead of dealing with the presence/absence of the primary plane in the higher level pre/post plane update code let's move all that into the fbc code itself. Now the higher level code doesn't have to think about FBC details anymore.
