Instead of the two status values struct pcmcia_device->p_state and state,
use descriptive bitfields. Most value-checking in drivers was invalid, as
the core now only calls the ->remove() (a.k.a. detach) function in case the
attachement _and_ configuration was successful.

Remove the assumption that pnp_register_driver() returns the number of devices
claimed.
parport_pc_init() does nothing with "count", so remove it. Then nobody uses
the return value of parport_pc_find_ports(), so make it void. Finally, update
pnp_register_driver() usage.

As can be seen from this patch, the avlab_*_[68]50 table entries are
identical to the plain avlab_* entries in every respect. Hence, there
is no need to list them separately in the pciserial_board nor
parport_pc_pci card tables - they can re-use the plain avlab_* entries.

Steinar H. Gunderson reported:
- For some reason, it detects the 9845 as a 9735 -- it appears this is
simply related to the ordering in parport_serial_pci_tbl[]. If we move
the 9845 up above the 9735, it prints out 9710:9845, but no change in
behaviour. (We didn't find out why this was the case; we left it alone
since it didn't affect our problem.)
- The card has no parallel port (at least no physical ones), yet it reports
(via its subsystem ID of 0x0014) one parallel port and four serial ports.
The probe for the parallel port fails, and the driver just aborts. Thus,
it doesn't find the serial ports.
Fix the debugging code to use dev_dbg, but don't bother displaying the
PCI ID of the detected board (that's accessible via other means.)
Also, arrange for parport_register() to return 0 even if it finds no
ports.

Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.
With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:
int (*probe) (struct pcmcia_device *dev);
void (*remove) (struct pcmcia_device *dev);
int (*suspend) (struct pcmcia_device *dev);
int (*resume) (struct pcmcia_device *dev);
