drm/amd/display: block passive dongle EDID Emulation for USB-C ports
[Why]
Emulating passive dongle on USB-C port causes issue on some asics.

Check for DP_IS_USB_C flag in bios parser and propagate it to
encoder features flags. If DP_IS_USB_C flag is set and it is trying to
emulate passive dongle, then return fail.
