The new method of probing dual fan support introduced in:
bf779aaf56ea ("platform/x86: thinkpad_acpi: Add dual fan probe")
While this commit says this works on the X1 Carbon 9th Gen, it actually
just results in hiding the second fan on my local machine. Additionally,
I'm fairly sure this machine powers on quite often without either of the
two fans spinning.
So let's fix this by adding back the dual fan quirk for the X1 Carbon 9th
Gen.
