drm/amd/display: Test HPD handler HDCP and detect
[WHAT]
handle_hpd_irq_helper() never ran its HDCP reset, its forced
connector branch or its successful re-detect branch.
[HOW]
Add a minimal HDCP work queue fixture and three tests: an HPD on
a driver that carries an HDCP work queue, which must reset the display
and flag the connector state; a connector forced on that reports no
connection and is emulated instead of detected; and a successful
re-detect that notifies userspace.
