Before pinctrl driver implemented, the uart0 controller reply on
bootloader for setting correct pin mux and configurations.
Now, let's add pinctrl property to uart0 of Bananapi-F3 board.

It would be nice to have a pinfunc header like
arch/arm/boot/dts/nxp/imx/imx7ulp-pinfunc.h.
It would reference and encode the data of "3.2 Pin Multiplex" in
https://developer.spacemit.com/documentation?token=An1vwTwKaigaXRkYfwmcznTXned

Not sure if it's worth the effort..
I gave up of introducing another macro, as it's exactly one to one mapping to
GPIO ID, which mean pin(x) -> GPIO_x
maybe I could put a comment at K1_PADCONF() to document this?
/* pin is same to the GPIO id according to 3.2 Pin Multiplex of User Manual */
#define K1_PADCONF(pin, func) (((pin) << 16) | (func))
does this sound good to you?

I'm weary the Manual may not exist on the site in the future or
will change formats. But it would be nice otherwise.

Sure, add it.
Also sorry for messing up the reply-to thing thunderbird is confusing.
