platform/x86: thinkpad_acpi: Add 2nd Fan Support for Thinkpad P50platform-drivers-x86-v4.17-1
The Thinkpad P50 has 2 fans. Add the 2FAN quirk so the tpacpi driver properly reports both fan speeds. Because the P50 doesn't report the version of its EC controller, we need to identify it by BIOS version (N1).
