drm/msm/dp: Support only IRQ_HPD and REPLUG interrupts for eDP
The panel-edp enables the eDP panel power during probe, get_modes
and pre-enable. The eDP connect and disconnect interrupts for the eDP/DP
controller are directly dependent on panel power. As eDP display can be
assumed as always connected, the controller driver can skip the eDP
connect and disconnect interrupts. Any disruption in the link status
will be indicated via the IRQ_HPD interrupts.
So, the eDP controller driver can just enable the IRQ_HPD and replug
interrupts. The DP controller driver still needs to enable all the
interrupts.
