Hi Haojian.

I'm not clear what this patch is intending to do.  I understand that
it removes the mmp-specific gpio support, but I looks like don't see the code
that replaces it, which would mean that applying this patch breaks
gpio on mmp platforms.

Am I missing something?

Be careful about this.  Turning on device tree support must not
disable booting on non-DT machines.
