drm/amd/display: Remove SDPIF_PORT_CONTROL programming for DCN31/35/42
[why & how]
DCN IP team recommends SDPIF_PORT_CONTROL=0 as POR value for APUs.
The new POR value ensures that DCHUBBUB will not disconnect the SDP port to DF unless it explicitly
receives the pre_cstate_req signal. SDPIF_PORT_CONTROL=1 will only be used for IPS entry sequences,
where it will be restored to 0 upon IPS exit.
