Subject: [PATCH v2] drm/rockchip: Set line flag config register in vop_crtc_enable
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.
Signed-off-by: Jeffy Chen <jeffy.chen@...k-chips.com>

Changes in v2:
Remove unused check and variables.
