drm/bridge: it6505: fix HDCP CTS KSV list wait timer
[ Upstream commit 9f9eef9ec1a2b57d95a86fe81df758e8253a7766 ]
HDCP must disabled encryption and restart authentication after
waiting KSV for 5s.
The original method uses a counter in a waitting loop that may
wait much longer than it is supposed to.
Use time_after() for KSV wait timeout.
