[ Upstream commit 8f7115c1923cd11146525f1615beb29018001964 ]
Commit 52824ca4502d ("drm/panel-edp: Better describe eDP panel delays") clarified the various delays used for eDP panels, tying them to the eDP panel timing diagram.
For Innolux N116BCA-EA1, .prepare_to_enable would be:
t4_min + t5_min + t6_min + max(t7_max, t8_min)
Since t4_min and t5_min are both 0, the panel can use either .enable or .prepare_to_enable.
As .enable is better defined, switch to using .enable for this panel.
Also add .disable = 50, based on the datasheet's t9_min value. This effectively makes the delays the same as delay_200_500_e80_d50.
