scsi: g_NCR5380: add HAS_IOPORT_MAP dependency

The driver was changed to call ioport_map, which breaks platforms that
cannot provide this function:

drivers/scsi/g_NCR5380.o: In function `generic_NCR5380_init_one.constprop.0':
g_NCR5380.c:(.text.generic_NCR5380_init_one.constprop.0+0x388): undefined reference to `ioport_map'

This adds a Kconfig dependency.
