platform/x86: thinkpad_acpi: Add quirk for ThinkPads without a fan
Some ThinkPad models, like the X1 Tablet 1st and 2nd Gen, are passively
cooled without any fan. Currently, an entry in /proc/acpi/ibm/fan is
nevertheless created, and misleadingly shows
status: enabled
speed: 65535
level: auto
This patch adds a TPACPI_FAN_NOFAN quirk definition and corresponding
handling to not initialize a fan interface at all.
For the time being, the quirk is only applied for X1 Tablet 2nd Gen
(types 20JB, 20JC; EC N1O...); further models (such as Gen1, types 20GG
and 20GH) can be added easily once tested.
Tested on a 20JCS00C00, BIOS N1OET58W (1.43), EC N1OHT34W.
