John Crispin 7f672e66f8 rampis: HLK-RM04 - Setup I2C as GPIO
The I2C function of the RT5350 SoC on the HLK-RM04 is used for GPIO1 and GPIO2.

Take note that the I2C_SD pin is GPIO1 on the RT5350 and is exposed on the HLK-RM04 as GPIO0
Likewise the I2C_SCLK pin is GPIO2 on the RT5350 and is exposed on the HLK-RM04 as GPIO1

 group   mode 1    mode 2   hlk-rm04 pin & export
  i2c    i2c_sd    gpio1   (pin 8, hlk-rm04:gpio0)
  i2c    i2c_sclk  gpio2   (pin 9, hlk-rm04:gpio1)
