Subject: [PATCH v3 5/7] drm/msm/dp: delete EV_HPD_INIT_SETUP

EV_HPD_INIT_SETUP flag is used to trigger the initialization of external
DP host controller. Since external DP host controller initialization had
been incorporated into pm_runtime_resume(), this flag become obsolete.
Lets get rid of it.

Changes in v3:
-- drop EV_HPD_INIT_SETUP and msm_dp_irq_postinstall()
