Guennadi Liakhovetski c36940e678 fbdev: sh_mobile_hdmi: add support for more precise HDMI clock configuration
The HDMI clock has to be reconfigured for different video modes. However, the
precision of the supplying SoC clock on SH-Mobile systems is often
insufficient. This patch allows to additionally reconfigure the parent clock
to achieve the optimal HDMI clock frequency, in case this is supported by the
platform.
