After my careful consideration, I did not do this.

If we do this,the corresponding members in all drivers must be also
#ifdef'd out,
including full-pinctrl drivers that do not care about memory footprint.

I do not like adding #ifdefs around to fix build errors found with
"make allyesconfig", "make randconfig".

I think it is a general strategy to not #ifdef out struct members.
