[PATCH v2 20/28] aarch64: Use NO_MATH_REDIRECT on pow_advsimd.c

There are calls to fma() which should be inlined and not redirected to __fma
with PLT avoidance. This issue is likely more widespread since various
math functions are inlined as a single instruction, and we don't want to
redirect such functions. It gets harder if one compiler inlines but another
doesn't, so a better general mechanism might be needed.

The patch looks good to me as a workaround.
