drm/amd/display: Populate DP2.0 output type for DML pipe

[Why]
DCN3.2 DML logic uses a new output type for DP2.0,
which will enable validation to pass for higher BW
timings that require DP2.0 link rates.

drm/amd/display: Add margin for max vblank time for SubVP + DRR

[Description]
- Incorporate FW delays as port of max VTOTAL calculated for
  SubVP + DRR cases (since it is part of the microschedule).
- Also add margin for the max VTOTAL possible for SubVP + DRR cases.
- Due to rounding errors in FW (integer arithmetic), the microschedule
  calculation can get pushed to the next frame (incorrectly) in cases
  where we use the max VTOTAL possible to complete the MCLK switch.
- When the rounding error occurs, we are only off by 1-2 lines,
  use 40us margin which is working consistently.

drm/amd/display: Fix reg timeout in enc314_enable_fifo

[Why]
The link enablement sequence can end up resetting the encoder while
the PHY symclk isn't yet on.

This means that waiting for symclk on will timeout, along with the reset
bit never asserting high.

This causes unnecessary delay when enabling the link and produces a
warning affecting multiple IGT tests.

[How]
Don't wait for the symclk to be on here because firmware already does.

Don't wait for reset if we know the symclk isn't on.

Split the reset into a helper function that checks the bit and decides
whether or not a delay is sufficient.

drm/amd/display: Fix FCLK deviation and tool compile issues

[Why]
Recent backports from open source do not have header inclusion pattern
that is consistent with inclusion style in the rest of the file. This
breaks the internal tool builds as well. A recent commit erronously
modified the original DML formula for calculating
ActiveClockChangeLatencyHidingY. This resulted in a FCLK deviation
from the golden values.

[How]
Change the way in which display_mode_vba.h is included so that it is
consistent with the inclusion style in rest of the file which also fixes
the tool build. Restore the DML formula to its original state to fix the
FCLK deviation.

  underflow
- Transitioning a phantom pipe directly into a

drm/amd/display: Consider dp cable id only when data is non zero

Cable ID is a DP2 feature to identify max certified link rate that
a cable can carry. The cable identification method requires both
cable and display hardware support. Since the specs comes late, it is
anticipated that the first round of DP2 cables and displays may not
be fully compatible to reliably return cable ID data. Therefore the
decision of our cable id policy is that if the cable can return non
zero cable id data, we will take cable's link rate capability into
account. However if we get zero data, the cable link rate capability
is considered inconclusive. In this case, we will not take cable's
capability into account to avoid of over limiting hardware capability
from users. The max overall link rate capability is still determined
after actual dp pre-training. Cable id is considered as an auxiliary
method of determining max link bandwidth capability.
