Clean up some of the DSS functions which select/get clock sources, use switch to select the clock source members since more clock sources will be introduced later on.
Remove the use of macro CONFIG_OMAP2_DSS_DSI in dispc_fclk_rate, use a dummy inline for function for dsi_get_pll_hsdiv_dispc_rate() instead for code clarity.
