[WHY]
DF PState and Voltage State are coupled such that one cannot be
raised without raising the other. This uses more power than
is necessary in high bandwidth scenarios.

[HOW]
Add logic to create a new bounding box state that allows for
DF PState to be low while Voltage State is high. Watermarks
vlevel calculation logic was also udpated to assume
state 1 contains the new optimized state.

and sets the I2c engine for HDCP use at release_engine.

[why]
Current pipe merge and split logic only supports cases where new
dc_state is allocated and relies on dc->current_state to gather
information from previous dc_state.

Calls to validate_bandwidth on UPDATE_TYPE_MED would cause an issue
because there is no new dc_state allocated, and data in
dc->current_state would be overwritten during pipe merge.

[how]
Only allow validate_bandwidth when new dc_state space is created.

DP link layer CTS specs updated to change the test parameters in test
4.2.1.1.
Before it requires source to delay 400us on aux no reply.
With the specs updates Errata5, it requires source to delay 3.2ms
(based on LTTPR aux timeout)
This causes our test to fail after updating with the latest test
equipment firmware.

[how]
the change is to allow LTTPR 3.2ms aux timeout delay by default.
And set back to 400us if LTTPR feature is not enabled.
We will set 3.2ms and always enable LTTPR non transparent mode
if LTTPR feature is enabled and LTTPR is present.

When we have single channel memory, we can not light up 2 4k displays
with a 1080p edp, because we don't have enough bw by a small margin.
this small margin comes from dcc meta being too large. We however don't
have this dcc meta when we create fake planes so, before the flip we
will not filter out the mode for 2 4k displays with a 1080p edp

[how]
Change get_default_swizzle_mode to something more general so we don't
end up with a separate function for every missing field in the fake
plane. Add a reasonable dcc meta to the fake plane when it is filled in,
so we filter out modes that don't have enough bandwidth. To do this, we
take the screen width and align it to 1024(8k 60)
