  pc: Add 'etc/boot-cpus' fw_cfg file for machine with more than 255 CPUs

Currently firmware uses 1 byte at 0x5F offset in RTC CMOS
to get number of CPUs present at boot. However 1 byte is
not enough to handle more than 255 CPUs.  So add a new
fw_cfg file that would allow QEMU to tell it.
For compat reasons add file only for machine types that
support more than 255 CPUs.

  exec: split cpu_exec_init()

Put in cpu_exec_initfn() what initializes the CPU,
and leave in cpu_exec_init() what adds it to the environment.

As cpu_exec_initfn() is called by all XX_cpu_initfn(), call it
directly in cpu_common_initfn().
cpu_exec_init() is now a realize function, it will be renamed
to cpu_exec_realizefn() and moved to the XX_cpu_realizefn()
function in a following patch.

  exec: move cpu_exec_init() calls to realize functions

Modify all CPUs to call it from XXX_cpu_realizefn() function.

Remove all the cannot_destroy_with_object_finalize_yet as
unsafe references have been moved to cpu_exec_realizefn().
(tested with QOM command provided by commit 4c315c27)

for arm:

Setting of cpu->mp_affinity is moved from arm_cpu_initfn()
to arm_cpu_realizefn() as setting of cpu_index is now done
in cpu_exec_realizefn(). To avoid to overwrite an user defined
value, we set it to an invalid value by default, and update
it in realize function only if the value is still invalid.
