arm64: dts: allwinner: a64-oceanic-5205-5inmfd: Enable GT911 CTP
Goodix GT911 CTP is bound with Oceanic 5205 5inMFD board.
The CTP connected to board with,
- SDA, SCK from i2c0
- GPIO-LD0 as AVDD28 supply
- PH4 gpio as interrupt pin
- PH11 gpio as reset pin
- X axis is inverted
- Y axis is inverted
