drm/amdgpu: fix comment about amdgpu.abmlevel defaults

Browse source 
Since 040fdcde28 ("drm/amdgpu: respect the abmlevel module parameter value
if it is set"), the default value for amdgpu.abmlevel was set to -1, or auto.
However, the comment explaining the default value was not updated to reflect
the change (-1, or auto; not -1, or disabled).

Clarify that the default value (-1) means auto.

Fixes: 040fdcde28 ("drm/amdgpu: respect the abmlevel module parameter value if it is set")
