[Why & How]
When MST config is unplugged/replugged too quickly, it can potentially
result in a scenario where previous DC state has not been reset before
the HPD link detection sequence begins. In this case, driver will
disable the streams/link prior to re-enabling the link for link
training.
There is a bug in the current logic that does not account for the fact
that current_state can be released and cleared prior to swapping to a
new state (resulting in the pipe_ctx stream pointers to be cleared) in
between disabling streams.
To resolve this, cache the original streams prior to committing any
stream updates.

We incorrectly ack all bytes get written when the reply actually is defer.
When it's defer, means sink is not ready for the request. We should

[How]
Only reply all data get written when receive I2C_ACK|AUX_ACK. Otherwise,
reply the number of actual written bytes received from the sink.
Add some messages to facilitate debugging as well.

There are several gaps that can result in SubVP being enabled with

to wrong predictions on future usage of SubVP.

- remove "prediction" logic in favor of tagging based on previous SubVP
usage
- block SubVP if current HW cursor settings are incompatible
- provide interface for DM to determine if HW cursor should be disabled
due to an attempt to enable SubVP
