drm/msm: dpu: Move pm_runtime_(get|put) from vblank_enable
There are 4 times that _dpu_crtc_vblank_enable_no_lock() is called:
1- crtc enable
2- crtc disable
3- crtc vblank enable
4- crtc vblank disable
When we enable or disable the crtc, we call drm_crtc_vblank_on and
drm_crtc_vblank_off respectively. That will gate vblank enables and
disables to only being called when the crtc is active. That means that
we can just enable/disable pm runtime in crtc enable/disable. This will
be beneficial in trying to eliminate blocking calls from the vblank call
chain.
Changes in v2:
- None
