drm/amd/display: add a quirk to enable eDP0 on DP1

Browse source 
[why]
some board designs have eDP0 connected to DP1, need a way to enable
support_edp0_on_dp1 flag, otherwise edp related features cannot work

[how]
do a dmi check during dm initialization to identify systems that
require support_edp0_on_dp1. Optimize quirk table with callback
functions to set quirk entries, retrieve_dmi_info can set quirks
according to quirk entries
