OMAP4: clock data: Change DSS clock aliases
DSS driver has used fck and ick clocks on OMAP2/3 to get DSS HW up and running, and also to get the pixel clock's source clock rate from the fck. On OMAP4 the clock data is set up in a different way, as there's no ick, dss_fck points to a fake clock which just affects DSS's MODULEMODE, and dss_dss_clk if the DSS_FCK. >From DSS driver's point of view the dss_fck sounds like an ick, and dss_dss_clk is the fck. While this is not entirely correct from HW point of view, especially for the ick, configuring the clock aliases that way makes DSS "just work" with OMAP4's clock setup. In the (hopefully near) future DSS driver will be reworked to use pm_runtime support which should clean up the clock code.
