[PATCH 2/3] arm64: dts: qcom: qrb4210-rb2: fix GPIO lookup flags for i2c SDA and SCL

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

The I2C GPIO bus driver enforces the SDA and SCL pins as open-drain
outputs but the lookup flags in the DTS don't reflect that triggering
warnings from GPIO core. Add the appropriate flags.
