Revert "HID: multitouch: Add support for lenovo Y9000P Touchpad"

commit 3d88ba86ba6f35a0467f25a88c38aa5639190d04 upstream.

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."
