drm/amd/display: Allow idle optimization after turning off all pipes

Browse source

[Why]
In certain D3 cases (BOCO / BOMACO) the hardware is reset but
software state still has idle_optimizations = true. This prevents
us from entering idle optimizations again if no display is connected.

[How]
In hw init, reset the idle optimization state, and allow idle
optimizations after all pipes have been turned off.
