That commit broke bsp/stm3210x. The cause is that we calls rtgui_system_init in rtgui_startup. But the calibration starts before rtgui_startup and rtgui_system_init. This lead to crash.
One way to deal with it is move rtgui_system_init out of rtgui_startup and call it manually. But it will affect other bsps. So just revert the "bad" commit.

If we do not calibrate the touch screen, GUI is unusable. This patch use a semaphore to block GUI thread until calibration finish.
