struct omap_dss_device contains DSS clock divisors. The idea is that the board file can pass precalculated divisors to the display driver. However, these divsors are no longer needed, as the omapdss driver can calculate the divisors during runtime.
This patch removes the divisors from omap_dss_device, and their uses from the dsi driver.
