[PATCH 5/7] mmc: meson-gx: avoid clock glitch when switching to DDR modes

Activating DDR in the Amlogic mmc controller, among other things, will divide the output clock by 2. So by activating it with clock on, we are creating a glitch on the output. Instead, let's deal with DDR when the clock output is off, when setting the clock. Signed-off-by: Jerome Brunet --- dri
