[PARISC] fix compile break caused by iomap: make IOPORT/PCI mapping functions conditional
The problem in
commit fea80311a939a746533a6d7e7c3183729d6a3faf

iomap: make IOPORT/PCI mapping functions conditional
is that if your architecture supplies pci_iomap/pci_iounmap, it expects
always to supply them. Adding empty body defitions in the !CONFIG_PCI
case, which is what this patch does, breaks the parisc compile because
the functions become doubly defined. It took us a while to spot this,
because we don't actually build !CONFIG_PCI very often (only if someone
is brave enough to test the snake/asp machines).
Since the note in the commit log says this is to fix a
CONFIG_GENERIC_IOMAP issue (which it does because CONFIG_GENERIC_IOMAP
supplies pci_iounmap only if CONFIG_PCI is set), there should actually
have been a condition upon this. This should make sure no other
architecture's !CONFIG_PCI compile breaks in the same way as parisc.
The fix had to be updated to take account of the GENERIC_PCI_IOMAP
separation.
