[v3] cpus: Move CPU code from exec.c to cpus-common.c

Commit Message

Philippe Mathieu-Daudé July 2, 2020, 10:40 a.m. UTC

This code was introduced with SMP support in commit 6a00d60127,
later commit 267f685b8b moved CPU list management to common code
but forgot this code. Move now and simplify ifdef'ry.
