This is a further improvement of HDMI quality on sh-mobile, by improving
clock precision. Currently on ap4evb PLLC2 is used as HDMI clock parent,
clocked at 594MHz, which provides exact 74.25MHz, required for 720p, when
divided through 8. However, for other video modes other parent clock
frequencies can provide better precision for the HDMI clock. This patch
adds necessary platform callbacks to reconfigure the parent clock and
implements this optimization in the sh clock framework and uses it on
ap4evb.
Thanks
Guennadi
