mb/lenovo/t520: Disable SATA2 and Thermal on W520

If a discoverable device (e.g. a PCI device) does not appear in the
devicetree (typically because it is removable), coreboot enables it
by default. Disable the SATA2 (device for SATA ports 4 and 5, which
is not used in AHCI mode) and Thermal devices on W520 as well. Both
devices were only disabled on the T520.

Tested, this change fixes a long boot time when using MrChromebox's
edk2 payload on the W520, likely related to the following errors:

    AHCI: Error interrupt reported PxIS: 40000001
    Non data transfer failed at retry 0
    AHCI: Error interrupt reported PxIS: 40000001
    Non data transfer failed at retry 1
    AHCI: Error interrupt reported PxIS: 40000001
    Non data transfer failed at retry 2
    AHCI: Error interrupt reported PxIS: 40000001
    Non data transfer failed at retry 3
    AHCI: Error interrupt reported PxIS: 40000001
    Non data transfer failed at retry 4
