[dts] [PATCH] framework: add argument for debug mode enable and disable

[Yong Liu <yong.liu@intel.com>]

From: Marvin Liu <yong.liu@intel.com>

When debug mode enable, before and after every send_expect function will
change signal handler. Althrough it only toke 0.x second, hundreds call of
send_expect will also take few minutes. This patch add one argument of dts to
enable and disable debug mode, and default debug mode will be disabled.
