drm/amd/display: Multiplane cursor position incorrect when plane rotated 



[Why]
When video plane is rotate the cursor position is incorrect and not
matching the desktop location.

[How]
When a plane is rotated 90 or 270 degrees, the src_rect.width and height
should be swapped when determining the scaling factor compared to the
dst_rect.
