Given the low-level interface varies from one flash-part

This patch fixes a problem of possible dropped interrupts. Currently,
the ibmvfc driver has a race condition where after ibmvfc_interrupt
gets run, the platform code clears the interrupt. This can result in
lost interrupts and, in worst case scenarios, result in command
timeouts. Fix this by implementing a tasklet similar to what the
ibmvscsi driver does so that interrupt processing is no longer done in
the actual interrupt handler, which eliminates the race.

netmos serial/parallel adapters come in different flavour differing only
by the number of parallel and serial ports, which are encoded in the
subdevice ID.

Last fix of Christian Pellegrin for 9855 2P2S broke support for 9855 1P4S,
and works only by side-effect for the first parallel port of a 2P2S, as
this first parallel port is found by reading the second addr entry of
(struct parport_pc_pci) cards[netmos_9855], which is not initialized, and
hence has value 0, which happens to be the BAR of the first parallel port.

netmos_9xx5_combo entry in (struct parport_pc_pci) cards[], which is used
for a 9845 1P4S must also be fixed for the parallel port support when
there are 4 serial ports because this entry currently gives 2 as BAR index
for the parallel port.  Actually, in this case, BAR 2 is the 3rd serial
port while the parallel port is at BAR 4.

I fixed 9845 1P4S and 9855 1P4S support, while preserving 9855 2P2S support,

- by creating a netmos_9855_2p entry and using it for 9855 boards with 2
  parallel ports : 9855 2P2S and 9855 2P0S boards,

- and by allowing netmos_parallel_init to change not only the number of
  parallel ports (0 or 1), but making it also change the BAR index of the
  parallel port when the serial ports are before the parallel port.

PS: the netmos_9855_2p entry in (struct pciserial_board)
pci_parport_serial_boards[] is needed because netmos_parallel_init has no
clean way to replace FL_BASE2 by FL_BASE4 in the description of the serial
ports in function of the number of parallel ports on the card.

Tested with 9845 1P4S, 9855 1P4S and 9855 2P2S boards.
