Revert "remove CONFIG_SERIAL_CPU_INIT"

This reverts commit 78efc4c36c68b51b3e73acdb721a12ec23ed0369.

The broadcast patch was reverted, so this commit should also
    be reverted. The reason for reverting the broadcast patch:

It turned out that sending IPIs via broadcast doesn't work on
    Sandybridge. We tried to come up with a solution, but didn't
    found any so far. So revert the code for now until we have
    a working solution.
