OMAPDSS: add clk_prepare_enable and clk_disable_unprepare
In preparation of OMAP moving to Common Clk Framework(CCF) change
clk_enable() and clk_disable() calls to clk_prepare_enable() and
clk_disable_unprepare() in omapdss. This can be safely done, as omapdss
never enables or disables clocks in atomic context.
