drm/amd/display: Cover hide_secondary_tile_from_userspace

Browse source

Add a KUnit test that drives amdgpu_dm_connector_detect() through the
amdgpu_dm_hide_secondary_tile_from_userspace() path using a sink that
requests disable_second_tile and a synthesized DisplayID tiled EDID at a
non-origin tile location, so the secondary Apple Studio Display tile is
hidden and the connector reports disconnected. Raises the helper coverage
from 44% to 100%.
