drm/amd/display: add a no_hpd link_encoder_funcs variant

Browse source

For link encoders without HPD (analog or LVDS), add a
link_encoder_funcs structure with no hpd enable callbacks.

The enable and disable hpd callbacks are currently not used
outside of a special case in debugfs which checks if the hpd
is valid before using it, but this will protect us if they
ever are.
