drm/amd/display: Default IPS to RCG_IN_ACTIVE_IPS2_IN_OFF
[Why]
Recent findings show negligible power savings between IPS2 and RCG
during static desktop. In fact, DCN related clocks are higher
when IPS2 is enabled vs RCG.
RCG_IN_ACTIVE is also the default policy for another OS supported by
DC, and it has faster entry/exit.
[How]
Remove previous logic that checked for IPS2 support, and just default
to `DMUB_IPS_RCG_IN_ACTIVE_IPS2_IN_OFF`.
