[PATCH v2] platform/x86: thinkpad_acpi: remove obsolete TODO comment

[Daniil Bulgar <bulgardaniil18@gmail.com>]

This patch removes the obsolete TODO comment regarding fan speed
presets in fan_write_cmd_speed. After discussion with the
maintainers, it was decided that fixed presets (low/medium/high)
are not suitable due to platform-specific variations.

v2:
 - Removed the preset implementation as requested by Mark Pearson
   and only removed the TODO comment.
v1: 
 - Initial attempt to implement low/medium/high presets.
