MA-8594 Add new get vsync time stamp interface. FB ioctl will acquire a global lock to protect FB resource. So, WAIT_FOR_VSYNC and PAN_DISPLAY ioctl will mutual lock each other. It will block the two ioctl executing in concurrence. Add /sys/class/graphics/fbx/vsync inode. It does the same thing with WAIT_FOR_VSYNC ioctl.
