drm/amd/display: Add more DC HW state info to underflow logging

2025-10-28T13:57:44+00:00

[Why] Debugging underflow issues frequently requires knowing the HW state at the time of underflow. To enable capturing this HW state information, interface functions are needed for the various DC HW blocks. [How] This change adds the interface functions to read HW state for the following DC HW blocks: - HUBBUB - HUBP - DPP - MPC - OPP - DSC - OPTC - DCCG Reviewed-by: George Shen Signed-off-by: Karen Chen Signed-off-by: Wayne Lin Tested-by: Dan Wheeler Signed-off-by: Alex Deucher
