Fixed the screen freeze issue for any frame with only FBT layer.
Bug: 33487853
Fixed by going through the normal post procedure, and creating the
corrsponding retire fence for the frame.
But actually display driver won't do real page flip by updating
the register(s) of Display Controller, to display the black screen.
Because, Anniedale Display Controller used in Fugu has a HARDWARE
bug that its pipe would hang if all of the attached RGB/YUV planes
are off.
Test: netflix, play movies, youtube
