OMAPDSS: HDMI: rewrite HDMI PLL calculation code
The code calculating HDMI PLL parameters has always been very confusing. Now that we are implementing a common PLL library for the DSS, it's important that the PLL code is understandable. This patch rewrites the calculation code, and removes a few hacks that were used there. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
