Log:
[PATCH] coreboot:  Don't loop forever waiting for HDA codecs

We shouldn't assume the presence of a working HDA codec, so put in
a reasonable timeout of 50usecs (timeout value borrowed from the kernel).
This makes SimNow work, since apparently though the codec is 
present in Simnow, it is non functional.
