drm/amd/display: add odm_slice_rect parameter in spl_in

[why]
OPP input rect aka odm slice rect is a hardware dependent parameter that
can't be determined by SPL software logic. Therefore we need to
explicitly pass odm slice rect in. So ODM slice rect calculation is
moved out of SPL.

[how]
add odm_slice_rect parameter in spl_in
