After the last review round I corrected the commit message
and use the sizeof of the target entries in the fmb_di_update()

from v4:
- commit message
- use sizeof target of the fmb_do_update

from v3:
- changed commit message according to Conny's comments

In s390-pci-inst.c
- simplify the fmb_do_update() to handle
  all cases from byte to quad. (Conny)

from v2:
In s390-pci-bus:
- Initialize the FMB Format.

In s390-pci-bus.h
- re-organization of the internal counters, having a table for the
  internal counters.

In s390-pci-inst.c
- Internal counters update (LD/ST/STB/RPCIT) is done always.
  even if the FMB if fmb_addr is NULL.
  AFAIU this respect the documentation which only states that FMB
  update is stopped.
- in mpcifc_service_call(), moved the setting of fmb_addr after
  the timer has been stopped.
- fmb_update((), use address_space_stq_be() to handle endianness
  when storing the FMB.
- define the format with 32 bits instead of one char and reserved
  chars, this is easier to handle the FMB copy.
- No update of the DMA fields inside the FMB, as stipulated by the
  documentation when format32 is 0.
