drm/amd/display: Don't change brightness for disabled connectors
[WHY]
When a laptop lid is closed the connector is disabled but userspace
can still try to change brightness. This doesn't work because the
panel is turned off. It will eventually time out, but there is a lot
of stutter along the way.
[How]
Iterate all connectors to check whether the matching one for the backlight
index is enabled.
