drm/amd/display: fix odm 2:1 policy not being applied consistently in 4k144 modes

[Why]
odm 2:1 policy is splitting the pipes in 4k144.
then in subvp code, we merge the pipes. but since the
 configuration is unsupported, we keep the pipes split

[How]
for unsupported subvp configuration, redo the dml and
 pipe split calls
