eMMC HS-DDR no longer works on the A80, despite it working when support for this developed. Disable it for now. Signed-off-by: Chen-Yu Tsai <wens@xxxxxxxx> --- Hi, When i worked on this it was working, but now it isn't. Unfortunately I don't have my old tree to do a proper bisect. I probably won't have time to dig into this issue before v4.6 release, so it's best to disable it on the A80 for now.
