drm/amd/display: Add debugfs entry for amdgpu_dm_visual_confirm
[Why]
DC provides a few visual confirmation debug options that can be
dynamically changed at runtime to help debug surface programming issues
but we don't have any way to access it from userspace.
[How]
Add the amdgpu_dm_visual_confirm debugfs entry.
It accepts a string containing the DC visual confirm enum value using
the debugfs attribute helpers.
The debugfs_create_file_unsafe can be used instead of
debugfs_create_file as per the documentation.
v2: Use debugfs helpers for getting and setting the value (Christian)
