[SRU][L][PATCH 0/1] Fix AMD gpu hang when screen off/on

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/2028740

[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.

Generic Jammy kernel doesn't need this commit because of no support of
AMD Phoenix GPU.
SRU for Lunar/oem-6.1 kernel.
