ENGR00243314 MX6 Sabreauto:Setup ipu di parent clock for HDMI case

We support smooth UI transition from Uboot splashscreen to Android
kernel for IPU1 DI1, so we don't set ipu1 di1 clock's parent clock
to be pll5 clock when kernel initializes clock tree. However,
sometimes, by using the same uboot and kernel, some platforms may
use ipu1 di1 to drive HDMI(e.g., MX6DL Sabreauto), which makes HDMI
pixel clock tree wrong. This patch sets the clock tree explicitly
in HDMI initializing hook function to address the issue. This patch
is for Android kernel only.
