Both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts.
Therefore irq_hpd handler should not issues either aux or sw reset
to avoid following unplug interrupt be cleared accidentally.

  drm/msm/dp: postpone irq_hpd event during connection pending state
  drm/msm/dp: unplug interrupt missed after irq_hpd handler
