When topology changes, before beginning a new HDCP authentication by
sending AKE_init message we need to first authenticate only the
repeater. Only after repeater authentication failure, it makes sense
to start a new HDCP authentication. Even though it made sense to not
enable HDCP directly from check_link and schedule it for later, repeater
authentication needs to be done immediately.

Make sure that the first read/write in hdcp2_authentication_key_exchange

since we do this to give docks and dp encoders some extra time to

Retry the first read and write to downstream at least 10 times
with a 50ms delay if not hdcp2 capable(dock decides to stop advertising
hdcp2 capability for some reason). The reason being that
during suspend resume Dock usually keep the HDCP2 registers inaccesible
causing AUX error. This wouldn't be a big problem if the userspace
just kept retrying with some delay while it continues to play low
values content but most userpace applications end up throwing an error
when it receives one from KMD. This makes sure we give the dock
and the sink devices to complete its power cycle and then try HDCP
