[PATCH] ARM: imx: fix missing include of 3ds_debugboard.h

The declaration of mxc_expio_init() was not included from the
header file "3ds_debugboard.h", so include it to fix the warning:

arch/arm/mach-imx/3ds_debugboard.c:155:12: warning: symbol 'mxc_expio_init' was not declared. Should it be static?
