[Impact]
AMD GPU hang when screen off/on.
error log:
kernel: [drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3

[Fix]
Keep a PHY active when detecting DP signal + DPMS active.

[Test]
Tested on 3 AMD platforms, GPU works fine.

[Where problems could occur]
Low risk, the fix is in v6.4-rc1.
