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

Changes for v3:
- Use 2.8v for reg_ldo_io0
Changes for v2:
- drop i2c1, bias-pull-up

You haven't fixed this, and you didn't either in the second patch.

Sorry, I interpreted previous comment to keep this pinctrl.
Since i2c1 node in sun50i-a64.dtsi doesn't have pinctrl attached to
it, added here like i2c0 is it something wrong?

If that's the only muxing option, it should be in the DTSI. If it's
not the only muxing option, then the name is wrong.
