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

Changes for v5:
- none
Changes for v4:
- drop i2c1 pinctrl
Changes for v3:
- Use 2.8v for reg_ldo_io0
Changes for v2:
- drop i2c1, bias-pull-up
