Add a safety check to runtime suspend to make sure all outstanding fences have signaled before we suspend. Doesn't fix any known issue. We already do this via the fence driver suspend function, but we just force completion rather than bailing. This bails on runtime suspend so we can try again later once the fences are signaled to avoid missing any outstanding work.

[Why] Cursor disappears for some SLS displays that are rotated 180 and 270 degrees. This occurs when there is no pipe split being done ( ex. 3 or more displays ).

2019-12-18drm/amd/display: fix 270 degree rotation for mixed-SLS modeSamson Tam
[Why] When we rotate 270 in mixed SLS mode, the recouts occupy the right side of the display. So all the recout_skip_v values are relative to the left side of the display. This causes adjust_vp_and_init_for_seamless_clip() to incorrectly increase the data->viewport.height for that recout. The rotation looks like the bottom half is duplicated twice. [How] recout.x values are being adjusted based on stream->timing.h_border_left. Instead of using h_border_left, use dst.x to represent the border.

Do all the calculations and then revert stream->timing.h_border_left and stream->dst.x back to their original values.
