(cherry picked from commit 92f68f6a1b297633159a3f3759e4dfc7e5b58abb)

SmartMux is a mechanism to switch the GPU being used for scanout in a
hybrid configuration. This is used for devices with an eDP and two GPUs.
This is only valid when the system has a physical switch (Multiplexer)
in the board to switch between the two GPUs.

When a graphically intensive workload like a game is being run, the
system can be switch the active display to the dGPU, so that we can
avoid copying the buffer from dGPU to APU for scanout. This helps with
latency and FPS. When power consumption is preferred, the system can be
switched to the APU.

[why & how]
UHBR link rate capable eDPs will use HPO for encoding. Need to pass
HPO stream and link encoder instances to DMCUB for Replay FSM to
know which instances to use.

[Why & How]
The tunnel BW validation code has changed to the new one.
Remove the unused code.
The DP tunneling overhead is not updated in SST.
Move updating DP tunneling overhead for both SST and MST.

[Why & How]
Add new function for DP tunnel bandwidth validation.
It uses the estimated BW and allocated BW to validate the timings.

[WHY]
These fields are read for the explicit purpose of detecting embedded LTTPRs
(i.e. between host ASIC and the user-facing port), and thus need to
calculate the correct DPCD address offset based on LTTPR count to target
the appropriate LTTPR's DPCD register space with these queries.

[HOW]
Cascaded LTTPRs in a link each snoop and increment LTTPR count when queried
via DPCD read, so an LTTPR embedded in a source device (e.g. USB4 port on a
laptop) will always be addressible using the max LTTPR count seen by the
host. Therefore we simply need to use a recently added helper function to
calculate the correct DPCD address to target potentially embedded LTTPRs
based on the received LTTPR count.

The BW zero allocation patch is no longer required.
Add a debug option to enable it in case we encounter an issue.

[Why]
Nits programming for SDR panel is only supported by VESA ABC.

[How]
1. Loose nits programming for OLED SDR panel with AMD ABC.
2. We support two ABC methods. Disable one before we program the other
   in case panel freaks out.
3. Update HDR judgement in setBR with a solider condition.

[Why & How]
It sent an error msg when it failed to read the DP tunneling DPCD field.
This should just be a warning msg. Use a DC log instead of a DM error msg.

[Why & How]
The original code only supports the tunneling for embedded one.
To support external tunneling feature, it needs to check
Tunneling_Support bit register.
