drm/amd/display: hpd rx irq not working with eDP interface
commit eeefe7c4820b6baa0462a8b723ea0a3b5846ccae upstream.
[Why]
This is the fix for the defect of commit ab144f0b4ad6
("drm/amd/display: Allow individual control of eDP hotplug support").
[How]
To revise the default eDP hotplug setting and use the enum to git rid
of the magic number for different options.
