Do those functions work if you use different GPIO pins for them?
Has something else got hold of GPIOs 20 and 21? What does "pinctrl get 20,21,26" show (raspi-gpio get 20,21,26 on older systems).
Can you post your full config.txt, just in case there's anything in there that might be changing the use of those GPIOs.
