[PATCH 3/3] drm/amd/display: "Enable IPS by default"

[Roman.Li at amd.com]

From: Roman Li <Roman.Li at amd.com>

[Why]
IPS was temporary disabled due to instability.
It was fixed in dmub firmware and with:
- "drm/amd/display: Add IPS checks before dcn register access"
- "drm/amd/display: Disable ips before dc interrupt setting"

[How]
Enable IPS by default.
Disable IPS if 0x800 bit set in amdgpu.dcdebugmask module params
