Cadence XCC is based off of a very old 4.2 gcc compiler, which didn't perfectly support C99 "inline" semantics with respect to cross-translation-unit inline linkage (which Zephyr does not use, our inlines are static only) and declaration order. Fix the one spot where we were calling an inline before its ALWAYS_INLINE definition, and add a flag to suppress the warning so CI's trying to build with XCC and -Werror don't flip out.
