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.

Subject: [PATCH 1/1] lenovo/t400: Enable all SATA ports
There are 2 SATA ports on the chassis of t400(s), but at least one dock for
t400 contains a port for (P/S)ATA device, and t400s has a eSATA port on its
chassis, and another one on its dock.
They have to be unmasked via device tree to use.
This patch unmasked all SATA ports found within t400s with factory firmware.
