[PATCH -next] asm-generic/iomap.h: add stubs for pci iomap/iounmap

From: Randy Dunlap <redacted>

When CONFIG_PCI is not enabled, CONFIG_EISA=y, and CONFIG_GENERIC_IOMAP=y,
drivers/net/3c59x.c build fails due to a recent small change to
<asm-generic/iomap.h> that surrounds pci_iomap() and pci_iounmap()
with #ifdef CONFIG_PCI/#endif.  Since that patch to iomap.h looks
correct, add stubs for pci_iomap() and pci_iounmap() with CONFIG_PCI
is not enabled to fix the build errors.

drivers/net/3c59x.c:1026: error: implicit declaration of function 'pci_iomap'
drivers/net/3c59x.c:1038: error: implicit declaration of function 'pci_iounmap'
