platform/x86: thinkpad_acpi: Add X1 Carbon Gen 9 second fan support

[ Upstream commit c0e0436cb4f6627146acdae8c77828f18db01151 ]

The X1 Carbon Gen 9 uses two fans instead of one like the previous
generation. This adds support for the second fan. It has been tested
on my X1 Carbon Gen 9 (20XXS00100) and works fine.
