Revert "HID: multitouch: Add support for lenovo Y9000P Touchpad"
This reverts commit 251efae73bd46b097deec4f9986d926813aed744.
Quoting Wang Yuli:
"The 27C6:01E0 touchpad doesn't require the workaround and applying it
would actually break functionality.
The initial report came from a BBS forum, but we suspect the
information provided by the forum user may be incorrect which could
happen sometimes. [1]
Further investigation showed that the Lenovo Y9000P 2024 doesn't even
use a Goodix touchpad. [2]
For the broader issue of 27c6:01e0 being unusable on some devices, it
just need to address it with a libinput quirk.
In conclusion, we should revert this commit, which is the best
solution."
