    drm/amd/display: fix the ability to use lower resolution modes on eDP
    
    commit 2de19022c5d7ff519dd5b9690f7713267bd1abfe upstream.
    
    On eDP we can receive invalid modes from dm_update_crtc_state() for
    entirely new streams for which drm_mode_set_crtcinfo() shouldn't be
    called on. So, instead of calling drm_mode_set_crtcinfo() from within
    create_stream_for_sink() we can instead call it from
    amdgpu_dm_connector_mode_valid(). Since, we are guaranteed to only call
    drm_mode_set_crtcinfo() for valid modes from that function (invalid
    modes are rejected by that callback) and that is the only user
    of create_validate_stream_for_sink() that we need to call
    drm_mode_set_crtcinfo() for (as before commit cb841d27b876
    ("drm/amd/display: Always pass connector_state to stream validation"),
    that is the only place where create_validate_stream_for_sink()'s
    dm_state was NULL).
