Subject: [PATCH 09/30] 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.
