[PATCH] arm64: alternatives: make apply_alternatives_vdso() static

[Mark Rutland]

We define and use apply_alternatives_vdso() within alternative.c, and
don't provide a prototype in a header. There's no need for it to be
visible outside of alternative.c, so mark it as static.

There should be no functional change as a result of this patch.
