Hi Yixun,

Honestly, I don't like the idea. I think it adds an unnecessary complexity.
I don't see the point of FUNCTION_EX(uart_ao_b, _z) when you could simply write 
FUNCTION(uart_ao_b_z) ... especially when there is just a couple of function per
SoC available on different domains.

A pinctrl driver can already be challenging to understand at first, let's keep
it simple and avoid adding more macros.
