[coreboot] CBMEM Console corruption with fsp_baytrail in coreboot 4.2

[Ben Gardner]

The following patch makes my system bootable with the timestamp
corruption issue.
It just stops the log flood.

I'm still a bit puzzled as to the root cause of the corruption.
Is there additional logging that would be useful?

Thanks,
Ben
