drm/amd/display: revert removing otg toggle w/a back when no active display

w/a use case:
- dual display, compliance, toggling between the displays
- switching between 120Hz 420 -> 144Hz 444 and vice versa
- switching between 144Hz -> 60Hz TMDS or vice versa

It'd typically involve TMDS in some capacity since that's the only link
signal we leave the OTG running but DIO/PHY off you can hit this in
cases where you have multiple displays as well it syncs with the first
active OTG, so if you had OTG[0] mapped and FIFO off you'd hit it even
if OTG[1] was mapped and had FIFO
