[Why]
1. It could hit bandwidth limitdation under single dimm
memory when connecting 8K external monitor.
2. IsSupportedVidPn got validation failed with
2K240Hz eDP + 8K24Hz external monitor.
3. It's better to filter out such combination in
EnumVidPnCofuncModality
4. For short term, filter out in dc bandwidth validation.
[How]
Force 2K@240Hz+8K@24Hz timing validation false in dc.

[Why&How]
- Implement interface to program DTBCLK DTO’s
according to reference DTBCLK returned by PMFW
- This is required because DTO programming
requires exact DTBCLK reference freq or it could
result in underflow

[Why]
If optimized init is done in FW. DCN init can be skipped in driver. This
need to be communicated between driver and fw and maintain backwards
compatibility.
[How]
Use DMUB scratch 0 bit 2 to indicate optimized init done in fw and
use DMUB scatch 4 bit 0 to indicate drive supports the optimized flow
so FW will perform it.

[Why]
When link training during engine recovery, ASSR might fail causing panel
mode to be reset to default. This should not happen for eDP as it
will prevent the panel from turning back on.
[How]
Added dp_panel_mode to struct dc_link to remember previously applied
panel mode. Do not reset panel mode to default while performing link
training if previously used panel mode = eDP.

FAMS enabled; if each of these commits were to set optimized_required,
then the user may see latency.
[HOW]
fw_based_mclk_switching is currently not used in dc->clk_mgr; use it
to track whether the current state has FAMS enabled;
if it has, then do not disable FAMS in prepare_bandwidth, and do not set
