arm64: dts: allwinner: a64-amarula-relic: Add GT5663 CTP node
Add Goodix GT5663 capacitive touch controller node on
Amarula A64-Relic board.
The CTP connected to board with,
- SDA, SCK from i2c1
- GPIO-LD0 as AVDD28 supply
- PH4 gpio as interrupt pin
- PH8 gpio as reset pin
- X axis is inverted
- Y axis is inverted
