sunxi: GPIO pin mux hardware-feature-specific function index defines
Each hardware feature exposed through the GPIO pin mux is usually using the same function index (for a given port), so there is no need to define one value per pin: one value per hardware feature per port is sufficient, avoids duplication and makes everything easier to understand.
