The pin functions are needed: for uart and SD/MMC.
The "only declare" part might be misleading: I meant that pinctrl-sun50i-a64.c
has no code, all logic is in the pinctrl-sunxi.c but actual pin functions
are not described in the device-tree but by structures in pinctrl-sun50i-a64.c
(which is almost a direct copy from Linux)
