gpio: Rename variable in core APIs
There is struct gpio *gc, *chip and *gpiochip, and yes I am responsible for some of the inconsistencies. I want this to be just gc everywhere for minimizing cognitive resistance when reading the code: more compact function signatures and less clutter. Purely syntactic changes intended. No semantic effects.
