scsi: g_NCR5380: Stop using scsi_module.c

Convert g_NCR5380 to use scsi_add_host instead of scsi_module.c Use
pnp_driver and isa_driver to manage cards.

In order to support multiple cards, new module parameter format is
introduced. The old parameters are kept for compatibility.

 This driver works as a module.
 When included as a module, parameters can be passed on the insmod/modprobe
 command line:
+  irq=xx[,...]	the interrupt(s)
+  base=xx[,...]	the port or base address(es) (for port or memory mapped, resp.)
+  card=xx[,...]	card type(s):
+		0 = NCR5380,
+		1 = NCR53C400,
+		2 = NCR53C400A,
+		3 = Domex Technology Corp 3181E (DTC3181E)
+		4 = Hewlett Packard C2502

+These old-style parameters can support only one card:
   ncr_irq=xx   the interrupt
   ncr_addr=xx  the port or base address (for port or memory
                mapped, resp.)
