drm/bridge: analogix_dp: fix no drm hpd event when panel plug in
The enum value of DP_IRQ_TYPE_HP_CABLE_IN is zero, but driver only
send drm hp event when the irq_type and the enum value is true.
if (irq_type & DP_IRQ_TYPE_HP_CABLE_IN || ...)
drm_helper_hpd_irq_event(dp->drm_dev);
So there would no drm hpd event when cable plug in, to fix that
just need to assign all hotplug enum with no-zero values.
