drm/amd/display: Test HPD RX downstream handling
[WHAT]
handle_hpd_rx_irq() left its whole post-detect block untested
apart from a failing re-detect, and never dispatched a CP_IRQ.
[HOW]
Add four tests covering a failing connection-type probe, a
connector forced on that is emulated instead of detected, a successful
re-detect that notifies userspace, and a CP_IRQ that must be handed to
the HDCP work queue for the connector that raised it.
