This is an attempt to further improve HDMI quality on sh-mobile by
optimizing clock rates. 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 for ap4evb.
Thanks
Guennadi
