cpu/x86/mp_init: use cb_err as status return type in remaining functions

Using cb_err as return type of mp_run_on_aps, mp_run_on_all_aps,
mp_run_on_all_cpus and mp_park_aps clarifies the meaning of the
different return values. This patch also adds the types.h include that
provides the definition of the cb_err enum and checks the return value
of all 4 functions listed above against the enum values instead of
either checking if it's non-zero or less than zero to handle the error
case.
