drm/amd/display: Allow UHBR Interop With eDP Supported Link Rates Table
[WHY]
eDP 2.0 is introducing support for UHBR link rates, however current eDP ILR
link optimization does not account for UHBR capabilities.
Either UHBR capabilities will be provided via the same 128b/132b rate DPCD caps
that are currently used on DP2.1, or Table 4-13 may be updated to include UHBR
rates.
[HOW]
Add extra Supported Link Rates table translations for UHBR10/13.5/20.
Update eDP link setting optimization search to be aware of 128b/132b DPCD
rate caps in order to unblock UHBR on panels with Supported Link Rates table.
