After commit 2be404486c05 ("HID: i2c-hid-of: Add reset GPIO support to i2c-hid-of"), the i2c-hid-of driver used by some mt8183 devices resets the touchscreen without having enough post-reset delay. This makes those touchscreen fail to get probed. Switch to Elan touchscreen driver, which has enough post-reset delay.
