What I meant is that the pins that the i2c-gpio nodes reference
are actually wired (inside the SoC) to the GSBI I2C controllers.

You'll notice that in drivers/pinctrl/qcom/pinctrl-apq8064.c,
there are bits like:

PINGROUP(6, gsbi3, NA, NA, NA, NA, NA, NA, NA, NA, NA),

which mean "function 0 is GPIO [implicitly in the macro], function
1 is mux to the GSBI controller"
