eDP implementation does not reuried to support hpd signal. Therefore
it only has either ST_DISPLAY_OFF or ST_CONNECTED state during normal
operation. This patch remove unnecessary dp_hpd_unplug_handle() for
eDP but still keep dp_hpd_plug_handle() to support eDP to either
booting up or resume from ST_DISCONNECTED state.
Fixes: 391c96ff0555 ("drm/msm/dp: Support only IRQ_HPD and REPLUG interrupts for eDP")
