arm64: dts: exynos: Add stmfts touchscreen node for TM2 and TM2E
TM2 and TM2E devices are provided with a ST-Microelectronics
Finger Tip S device with small differences:
- screen size
- TM2E uses the stmfts also as a touchkey for "back" and "menu"
In this commit the initial value of the interrupt line is set to
EXYNOS_PIN_PULL_UP as the interrupt is triggered when the line
goes down.
