We need to set vop config done after update line flag config, it's a
new requirement for chips newer than rk3368.
Since we would only use line flag irq for vact_end, let's move it to
vop_crtc_enable.
v2: Remove unused check and variables.

Changes in v2:
Remove unused check and variables.

Hi Jeffy,
v1 was already applied. Please send a follow-on patch to clean this up.
