    Revert wbind added to the reset_vector
    This change reverts :
    Change Id I4fdb281b2b684ab5fea999aae28ca08dce24da4d
    The wbinvd (or invd) should not be needed at the reset vector. It
    causes problems with some CPUs AP init. If there is a problem with
    a specific CPU and it must be done at this location, it should be
    added conditionally.
