[ Upstream commit 5a6f0dbe621a5c20dc912ac474debf9f11129e03 ]
Move the DMI quirks for upside-down mounted Goodix touchscreens from drivers/input/touchscreen/goodix.c to drivers/platform/x86/touchscreen_dmi.c, where all the other x86 touchscreen quirks live.
Note the touchscreen_dmi.c code attaches standard touchscreen device-properties to an i2c-client device based on a combination of a DMI match + a device-name match. I've verified that the: Teclast X98 Pro, WinBook TW100 and WinBook TW700 uses an ACPI devicename of "GDIX1001:00" based on acpidumps and/or dmesg output available on the web.
This patch was tested on a Teclast X89 tablet.
