imx6 and rockchip rk3288 and JZ4780 (Ingenic Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly difference, such as phy pll configuration, register width(imx hdmi register is one byte, but rk3288 is 4 bytes width), 4K support(imx6 doesn't support 4k, but rk3288 does), clk useage,and the crtc mux configuration is also platform specific.

To reuse the imx hdmi driver, split the platform specific code out to dw_hdmi-imx.c.
