[coreboot] SB600 flashrom hang (Patch)

If the usec_delay() is called, the programming action will be unbearably
slow. I haven't got a way to solve this.

I would like to improve the busy wait loop. Is 1 ms the desired
timeout? In that case the myusec_delay(1000) call is good.

Is it better if the delay is longer or shorter than 1 ms?
