OMAPDSS: DISPC: Remove Fake VSYNC support

Browse Source 
Fake VSYNC support is a hack and has some bugs in it. It isn't used by any user
of DSS. Remove Fake VSYNC support. For DSI command mode and RFBI panels, a user
of DSS should wait for the completion of a frame by using the panel driver's
sync op.

If this is selected, DSI will generate a fake DISPC VSYNC interrupt
when DSI has sent a frame. This is only needed with DSI or RFBI
displays using manual mode, and you want VSYNC to, for example,
time animation.
