[PATCH 20/21] drm/amd/display: Enable idle workqueue for more IPS modes

From: Leo Li <sunpeng.li at amd.com>

[Why]

There are more IPS modes other than DMUB_IPS_ENABLE that enables IPS. We
need to enable the hotplug detect idle workqueue for those modes as
well.

[How]

Modify the if condition to initialize the workqueue in all IPS modes
except for DMUB_IPS_DISABLE_ALL.

Fixes: 514fd3e75d90 ("drm/amd/display: Determine IPS mode by ASIC and PMFW versions")
