fbdev: omapfb: Remove some deadcode

Browse Source 
commit f76ee892a9 ("omapfb: copy omapdss & displays for omapfb")
took a copy of the omapdrm code into omapfb, however at that point
a couple of functions were already unused at that point.

Remove dispc_mgr_get_clock_div() and dispc_enable_fifomerge() from
the omapfb copy.
