lenovo/t400: Enable all SATA ports (add persmule's patch)
See:
<https://lists.nongnu.org/archive/html/libreboot/2016-08/msg00063.html>
This enables all SATA ports, allowing full T400s compatibility. T400s already
works just fine, when flashing a T400 ROM, but not all SATA ports were usable.
The specific patch is here:
<https://lists.nongnu.org/archive/html/libreboot/2016-08/txtgT_L8DC94R.txt>
There was also this patch, which coreboot actually adapted upstream:
<https://lists.nongnu.org/archive/html/libreboot/2016-08/txtMXyws85Q_P.txt>
Yes, this patch was submitted in 2016. I overlooked it, during all this time.
