drm/amd/display: Workaround for some legacy DP-VGA dongles
[Why]
Maximum resolution is 1440*900 when connecting to FHD monitor via some DP-VGA
dongles. The display EDID reading fails over AUX/I2C via DP->VGA dongle, and
this leads to the maximum resolution 1920*1080 cannot be obtained from EDID.
[How]
Provide a workaround for some legacy DP-VGA dongles with a longer aux delay.
