PCI: Stub __pci_ioport_map() for arches that don't support it at all
When building OpenRISC PCI, which has no ioport_map(), we get the following
build error:
lib/pci_iomap.c: In function 'pci_iomap_range':
CC drivers/i2c/i2c-core-base.o
./include/asm-generic/pci_iomap.h:29:41: error: implicit declaration of function 'ioport_map'; did you mean 'ioremap'? [-Werror=implicit-function-declaration]
29 | #define __pci_ioport_map(dev, port, nr) ioport_map((port), (nr))
| ^~~~~~~~~~
lib/pci_iomap.c:44:24: note: in expansion of macro '__pci_ioport_map'
44 | return __pci_ioport_map(dev, start, len);
| ^~~~~~~~~~~~~~~~
Add a NULL definition of __pci_ioport_map() for architectures that do not
support ioport_map().
