hdmi:rk3368/rk3288: set color format in avi to RGB before mute output.

Browse Source 
For some sink, it will random recognize YCbCr as RGB when swithing
        hdmi format, picture will covered with purple. If we set color
        fomat in avi to RGB and reset avi to YCbCr, picture will be ok. So
        we set avi to RGB before mute ouput when switching hdmi format.
