ENGR00141732 SDMA: Fix bootup stop at sdma firmware loading

Linux 2.6.38 kernel bootup slow, it stopped at sdma firmware
loading for about one minute.

It is caused by firmware store on rootfs lib/firmware directory,
while sdma initialization happens before rootfs mounted.

To fix it, we have to build firmware in kernel image.
