    I add these bindings for dw-hdmi core, because
   properities like reg, interrupts, ddc-i2c-bus, reg-io-width are used
   by dw-hdmi core, but properities like compatible, gpr,clk, are platform
   specific , they are handled by the platform code like dw_hdmi-imx.c
   and described in platform specific dt binds like /imx-drm/hdmi.txt
