Currently selective fetch area calculation ends up as bogus area in
at least following cases:

1. Updated plane is partially or fully outside pipe area
2. Big fb with only part of memory area used for plane

These end up as y1 = 0, y2 = 4 or y2 being outside pipe area. This
patch set addresses these by ensuring update area is within pipe area
or by falling back to full update.

v5:
 - pipeA -> "pipe %c", pipe_name(crtc-pipe)
v4:
 - draw_area -> pipe_src
 - drm_dbg_once dropped and drm_info_once used instead
v3:
 - Add drm_dbg_once* and use it when sel fetch area calculation fails
 - Move drm_rect_intersect to clip_area_update
v2:
 - Update commit message of first patch
 - Set damaged_area x1 and x2 during initialization
