arm64: dts: mediatek: mt8183: Switch to Elan touchscreen driver

Browse source 
After commit 2be404486c ("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.
